Value of cos 180 degrees can be obtained with the help of unit circle and trigonometric sin and cos functions from other angles like 0, 90, and 270 degrees. Learn cosine pi (π) value with derivation at BYJU'S.
It is interesting to note that the value of cos changes according to the quadrants. In the above table, it can be seen that cos 120°, 150° and 180° have negative values while cos 0°, 30°, etc. have positive values. For cos, the value will be positive in the first and the ...
1. The value of cosπ is -1.2. In trigonometry, an angle of π radians corresponds to 180 degrees, so cosπ represents the value of cos180, which is -1.3. When the terminal side of an angle of π radians lies on the negative x-axis, the values of the trigonometric f...
Compute the cos inverse of the value from Step 1: arccos(x). You may want to use an online cos inverse calculator to do that. Subtract the value obtained in Step 2 from π, i.e., compute π - arccos(x). This is your answer! We've used here the formula arccos(-x) = π - ...

TheCOSfunction in Excel expects the radian unit of angle, not the degree value, so degree values will need to be converted into radian units by multiplying the angle by (pi/180). Pay attention to the power over trigonometry functions, ie whether the power is over the angle or over the ...
Does cosine repeat? The cosine function is periodic with a period of 2π radians (or 360° in degrees), meaning its values repeat at regular intervals due to the unit circle’s periodic nature. Trigonometry CalculatorsMath Calculators
