How to Find Cos 3° in Terms of Other Trigonometric Functions? Usingtrigonometry formula, the value of cos 3° can be given in terms of other trigonometric functions as: ±√(1-sin²(3°)) ± 1/√(1 + tan²(3°)) ± cot 3°/√(1 + cot²(3°)) ...
1. Arc Degrees (Radians)When measured in radians, we need to consider the angle's relationship to the unit circle. To find cos(3) in radians, we typically refer to the sine and cosine of multiples of π/6, since 3 radians is equivalent to 3 * π/6. By examining the un...
