What is a good calculator for trigonometry?
Any calculator sold as a "scientific calculator" has the basic trigonometric functions (sin, cos, tan) and the inverse trigonometric functions (arc-sin, arc-cos, arc-tan). That's about all you need.You can also use the calculator that comes on your computer - for example, in Windows, press Windows-R, and then type "calc". You may have to change the calculator mode, to "scientific calculator". Yet another option is a spreadsheet, for example, Excel. Note that in Excel, angles are expressed in radians; if you want degrees, you also need the special functions to convert degrees to radians, or radians to degrees. However, if you want to do your homework while you are NOT at your computer, you are better off buying a calculator.
How do you solve COS?
To solve for the cosine (COS) of an angle, you can use the unit circle, where the cosine of an angle corresponds to the x-coordinate of the point on the circle at that angle. Alternatively, you can use trigonometric identities or the cosine function on a scientific calculator by inputting the angle in degrees or radians. For specific problem solving, using the cosine rule in triangles may also be applicable to find unknown sides or angles.
How do you find conjugate of cos z?
To find the conjugate of ( \cos z ) for a complex number ( z = x + iy ) (where ( x ) and ( y ) are real numbers), you can use the formula for the cosine of a complex argument: [ \cos z = \cos(x + iy) = \cos x \cosh y - i \sin x \sinh y. ] The conjugate of ( \cos z ) is obtained by taking the complex conjugate of the expression, resulting in: [ \overline{\cos z} = \cos x \cosh y + i \sin x \sinh y. ]

How you find six trig functions of 180 degree?
To find the six trigonometric functions of 180 degrees, we can use the unit circle. At 180 degrees, the coordinates of the point on the unit circle are (-1, 0). Thus, the sine function (sin) is 0, the cosine function (cos) is -1, and the tangent function (tan) is 0. Consequently, the values for the six trig functions are: sin(180°) = 0, cos(180°) = -1, tan(180°) = 0, csc(180°) is undefined, sec(180°) = -1, and cot(180°) is undefined.
How do you find cos 60?
cos(60) = 0.5 The simplest way is to use a calculator.
How do you compute the secant of 2?
secant(2) =1/cos(2) for which you can use a calculator. However, you need to know whether the angle is measured in degrees or radians.
What is the exact value of COS 40.7 40.7?
The exact value of (\cos(40.7^\circ)) is not a simple rational number or a well-known trigonometric value. To find its numerical approximation, you can use a calculator, which gives (\cos(40.7^\circ) \approx 0.7578). For precise applications, it's best to use a calculator or software that can compute trigonometric functions.
Find a cos of some value?
To find the cosine of a specific angle, you can use a scientific calculator or refer to the unit circle. For example, the cosine of 0 degrees (or 0 radians) is 1, while the cosine of 90 degrees (or π/2 radians) is 0. Additionally, you can use trigonometric identities or tables for common angles such as 30 degrees (√3/2), 45 degrees (√2/2), and 60 degrees (1/2).

How do you find the cosine of a number?
Use a calculator or computer. You could convert the angle from degrees to radians. Then, if the angle is x radians, cos(x) = 1 - x^2/2! + x^4/4! - x^6/6! - ... But be warned: this is an infinite series.
What is sin cos tan csc sec cot of 135 degrees?
All those can be calculated quickly with your calculator. Just be sure it is in "degrees" mode (not in radians). Also, use the following identities: csc(x) = 1 / sin(x) sec(x) = 1 / cos(x) cot(x) = 1 / tan(x) or the equivalent cos(x) / sin(x)

What is the angle for cos equals 0.2874?
Well, isn't that just a happy little question! To find the angle for cos equals 0.2874, you can use the arccos function on a calculator. This function will give you the angle in radians where cos of that angle is equal to 0.2874. Just remember to breathe, take your time, and enjoy the process of discovering the beauty of mathematics.
How do you solve cosine 140?
Well, the usual way would be to use a scientific calculator - one that has support for trigonometric functions such as cosine. Make sure the calculator is set to "degrees", since I assume the "140" represents degrees. Of course you might also use the infinite series for the cosine function (which is basically what the calculator does). Convert the angle to radians, then use the infinite Tailor series: cos x = 1 - x2/2! + x4/4! - x6/6! + ...
What are the multiples of 15 up to 1000?
15*1 to 15*66. Use your calculator to find them.15*1 to 15*66. Use your calculator to find them.15*1 to 15*66. Use your calculator to find them.15*1 to 15*66. Use your calculator to find them.
How do you find cos and sin if angles are given?
There is nothing in the question to justify an assumption that the angle is a vertex of a triangle. Even if it were, there is no justification for assuming that it is a right angled triangle. So the use of ratios of sides of a triangle are totally inappropriate.In the circumstances, the only realistic way is to use a calculator. Make sure that the calculator's mode is set to the correct measurement unit for the angle - degrees or radians - and use the cosine or sine function.Spreadsheets such as Excel only use angles measured in radians. So, if given the angle in degrees, multiply the value by pi/180 and then use the appropriate trigonometric function.
