How To Find The Derivative Of Tanx Using The Quotient Rule In Calculus

d/dx tanx

sec^2(x)

The derivative of tanx with respect to x can be found by applying the quotient rule.

Recall that the quotient rule states:

If y = f(x)/g(x), then y’ = (f'(x)g(x) – f(x)g'(x))/[g(x)]^2

Let f(x) = sinx and g(x) = cosx, then

tanx = sinx/cosx

Now, applying the quotient rule:

[tanx]’ = [(sinx)’cosx – sinx(cosx)’]/(cosx)^2
= [cosx*cosx + sinx*sinx]/(cosx)^2

Recall that sin²x + cos²x = 1, so we can simplify:

[tanx]’ = 1/(cosx)^2

Therefore, the derivative of tanx with respect to x is 1/(cosx)^2.
