What is the value of Cos 1?
The inverse cos of 1 is equal to o degrees. You can find this answer by knowing what angle measurement has cos equal to a value of 1.
What is cos in a math problem?
Its a ratio in a right angle triangle, cos angle = adjacent / hypotonuse.
I have magnitude and angle how can find a b and a Dot b a 3 angle 45 b 5 angle 90 Find A B A dot B?
a = 3/sqrt(2)*i + 3/sqrt(2)*jb = 5ja.b = |a|*|b|*cos(q)= 3*5*cos(45) = 15/sqrt(2)
How do you find hypotenuse c angle a equals 30 deg side b equals 5 mm?
To find the hypotenuse with angle a and side b, we use the identity below:cos(a) = b/cWe have a and b, and to find c, we multiply both sides by c and divide both sides by cos(a):c = b/cos(a)c = 5/cos(30)c = 32.41460617mm
The tanget of an angle equals the ratio of the?
Tan(ANGLE) = Sin(ANGLE) / Cos(ANGLE).
What is cos of a negative angle?
The cosine function is an even function which means that cos(-x) = cos(x). So, if cos of an angle is positive, then the cos of the negative of that angle is positive and if cos of an angle is negative, then the cos of the negative of that angle is negaitive.
How do you use calculator to find cos degrees?
To find the cosine of an angle in degrees using a calculator, first ensure that the calculator is set to degree mode (not radians). Enter the angle in degrees, then press the "cos" button. The calculator will display the cosine value for that angle. For example, to find cos(60°), input 60, select "cos," and the result will be 0.5.
What is a quadrantal angle?
A Quadrantal angle is an angle that is not in Quadrant I. Consider angle 120. You want to find cos(120) . 120 lies in quadrant II. Also, 120=180-60. So, it is enough to find cos(60) and put the proper sign. cos(60)=1/2. Cosine is negative in quadrant II, Therefore, cos(120) = -1/2.

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 would you find out the sin tan and cos of right angle triangle?
sin, tan and cos can be defined as functions of an angle. But they are not functions of a triangle - whether it is a right angled triangle or not.
How do you find the diagonal of a rectangle if you know the length and the angle?
You need to use trigonometry cosine (angle) = length/diagonal diagonal = length/cos(angle)
What is cos in a math problem?
Its a ratio in a right angle triangle, cos angle = adjacent / hypotonuse.
Find hypotenuse only using adjacent and angle?
Use trigonometry and the cosine ratio: cos = adj/hyp and when rearraged hyp = adj/cos
What is Relation between loss angle and Power factor?
Power factor = cos (angle)PF=cos @
What is cos2 A?
Cos(2A) = Cos(A + A) Double Angle Indentity Cos(A+A) = Cos(A)Cos(A) - Sin(A)Sin(A) => Cos^(2)[A] - SIn^(2)[A] => Cos^(2)[A] - (1 - Cos^(2)[A] => 2Cos^(2)[A] - 1
