To find the cosine of an angle, you divide the adjacent side of the triangle by the hypotenuse. A helpful hint for the trig functions of sin, cos, and tan is SOH CAH TOA. It's a helpful way to remember what to do. For Sine you divide the opposite side by the hypotenuse. In Tangent, you divide the opposite side by the adjacent side.
What else can I help you with?
At what angle measure are the sin and the cosine equal?
45 degree
What is cosine cubed?
It is cosine*cosine*cosine.
What is the measure of an angle whose cosine ratio is known called?
Boot E.S. Maximus.
The inverse of the cosine function?
Inverse of Cosine is 'ArcCos' or Cos^(-1) The reciprocal of Cosine is !/ Cosine = Secant.
How do you find the angles of an acute triangle?
Measure two of them. Then the third is 180 degrees minus the two that you know. Or measure the lengths of the sides and use the cosine rule.
What is the measure of an angle whose cosine 0.5?
The measure of an angle whose cosine is 0.5 is 60 degrees (or (\frac{\pi}{3}) radians) in the first quadrant. Additionally, in the context of the unit circle, the angle can also be 300 degrees (or (\frac{5\pi}{3}) radians) in the fourth quadrant.
What are inverse sine inverse cosine and inverse tangent used for?
to find the measure of an angle. EX: if sin A = 0.1234, then inv sin (0.1234) will give you the measure of angle A
What is cosine of 1?
Cosine of 1 degree is about 0.999848. Cosine of 1 radian is about 0.540302.
What is the measure of an angle in a right angled triangle found by dividing the length of the side adjacent to the angle by the length of the hypothenuse?
cosine
How does the tangent function relate to sine and cosine?
Tangent = sine/cosine provided that cosine is non-zero. When cosine is 0, then tangent is undefined.
What is an inverse cosine?
The inverse of the cosine is the secant.
Reciprocal of a cosine?
Reciprocal of Cosine is Secant
