This video covers MA 101 – Calculus I, Module 2, Section 2.4: Derivatives of Trigonometric Functions.

We explain and apply the most important differentiation rules for trigonometric functions:

d/dx (sin x) = cos x

d/dx (cos x) = –sin x

d/dx (tan x) = sec²x

d/dx (cot x) = –csc²x

d/dx (sec x) = sec x · tan x

d/dx (csc x) = –csc x · cot x

🎯 By the end of this lesson, you will be able to differentiate all six basic trigonometric functions.
