Let h (x)=f (x)/g (x), where both f and g are differentiable and g (x)≠0. The quotient rule states that the derivative of h (x) is hʼ (x)= (fʼ (x)g (x)-f (x)gʼ (x))/g (x)². It is provable in many ways by ...

Webcos^2 x + sin^2 x = 1. sin x/cos x = tan x. You want to simplify an equation down so you can use one of the trig identities to simplify your answer even more. some other identities (you will learn later) include -. cos x/sin x = cot x. 1 + tan^2 x = sec^2 x. 1 + cot^2 x = csc^2 x. hope this helped! WebExample 1: Determine the value of sin 150° using cofunction identities. Solution: To find the value of sin 150°, we will use the formula sin θ = cos (90° - θ). So, we have sin 150° = cos (90° - 150°) = cos (-60°) = cos (60°) --- [Because cos (-x) = cos x for all x.] = 1/2 --- [Because cos 60° = 1/2] Answer: sin 150° = 1/2
