Derivative of trig functions proof
WebDerivatives of Tangent, Cotangent, Secant, and Cosecant We can get the derivatives of the other four trig functions by applying the quotient rule to sine and cosine. For instance, d d x ( tan ( x)) = ( sin ( x) cos ( x)) ′ = cos ( x) ( sin ( x)) ′ − sin ( x) ( cos ( x)) ′ cos 2 ( x) = cos 2 ( x) + sin 2 ( x) cos 2 ( x) = 1 cos 2 ( x) = sec 2 ( x). WebThe basic trigonometric functions include the following 6 functions: sine (sin x), cosine (cos x), tangent (tan x), cotangent (cot x), secant (sec x), and cosecant (csc x). All these …

WebJan 17, 2024 · Use the inverse function theorem to find the derivative of g(x) = 3√x. Solution The function g(x) = 3√x is the inverse of the function f(x) = x3. Since g′ (x) = 1 f′ (g(x)), begin by finding f′ (x). Thus, f′ (x) = 3x3 and f′ (g(x)) = 3(3√x)2 = 3x2 / 3 Finally, g′ (x) = 1 3x2 / 3 = 1 3x − 2 / 3.
