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 calculate sin20?
You need to use a calculator or computer. The answer will depend on whether the angle is measured in degrees or radians.
Use a calculator to find tan 27 round to the nearest thousandth?

Why only cos theta is used in vector functions?
It's not. Cos(Θ) only gives you the x-component of a vector. In order to find its y-component, you also need to use sin(Θ).
How do you find the angle measurements of a triangle if you have all the side lengths- which SOH CAH TOA do i use?
with all the sides, you could use any, use SOH :( sin of angle = opposite / hypotonuse)assuming its a right angle triangle, then select either of the (non right angle) angles, divide the length of the side opposite this angle by the length of the hypotonuse ( longest side, opposite the right angle), then find the inverse SIN of this number on your calculator, this is the angle. Since total internal angles always = 180 degrees, and right angle = 90 degrees then final angle is calculated angle subtracted from 90 degrees.
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.

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 solve the equation negative 3 cos t equals 1 in the interval from 0 to 2 pi?
Isolate cos (t): cos(t)=1/3. Use a calculator from here because the answer is not an integer or a simple number.
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.
How do you calculate radians from degrees?
