# SQA Higher Maths Differentiation of trigonometric functions

This page covers the following topics:

1. Differentiating trigonometric functions

Equations involving trigonometric functions can be differentiated using the basic rules of differentiation by using the following results: d(sinx)/dx = cosx, d(cosx)/dx = āsinx and d(tanx)/dx = secĀ²x.

# 1

Find a function for the slope for the given graph.

# 2

Find the derivative of y = 8tanĀ³x.

# 3

Find the derivative of the following function: f(x) = 5x/(1 + xĀ²) ā cosx.

# 4

Find the derivative of y = tanx + 8x.

# 5

Differentiate y = sinā“x.
