1. The problem statement, all variables and given/known data how is the differential of 1+tan2(4x) 8*tan(4x)*sec2(4x) 2. Relevant equations 3. The attempt at a solution So 1 differentiates to 0 (we can now ignore this) tan2(4x) differentiates to 2*tan(4x)*sec2(4x)? BRING POWER FORWARD, DOWN POWER BY 1, DIFFERENTIATE TERM IN BRACKET by the chain rule?
