WebJul 23, 2024 · Example 1. 1. Evaluate the following. The angle is not commonly found as an angle to memorize the sine and cosine of on the unit circle. 2. Write the expression in terms of common angles. We know the cosine and sine of common angles like and It will therefore be easier to deal with such angles. [2] 3. WebThe arctangent of x is defined as the inverse tangent function of x when x is real (x ∈ℝ). When the tangent of y is equal to x: tan y = x. Then the arctangent of x is equal to the inverse tangent function of x, which is equal to y: arctan x= tan-1 x = y. Example. arctan 1 = tan-1 1 = π/4 rad = 45° Graph of arctan. Arctan rules
