Find the Derivative - d/dx tan((pix)/2)

Problem

d(tan((π*x)/2))/d(x)

Solution

1. Identify the outer function and the inner function to apply the Chain Rule. The outer function is tan(u) and the inner function is u=(π*x)/2

2. Differentiate the outer function with respect to the inner function. The derivative of tan(u) is sec2(u)

d(tan(u))/d(u)=sec2(u)

3. Differentiate the inner function with respect to x The derivative of (π*x)/2 is π/2

d()/d(x)(π*x)/2=π/2

4. Apply the Chain Rule by multiplying the derivative of the outer function by the derivative of the inner function.

d(tan((π*x)/2))/d(x)=sec2((π*x)/2)⋅π/2

5. Simplify the expression by moving the constant factor to the front.

π/2*sec2((π*x)/2)

Final Answer

d(tan((π*x)/2))/d(x)=π/2*sec2((π*x)/2)
