Expert Answer:

integral cos e c to the power of 4 x d x
equals integral cos e c squared x cos e c squared x d x
equals integral left parenthesis 1 plus c o t squared x right parenthesis cos e c squared x d x
l e t space c o t x equals z rightwards double arrow negative cos e c squared x d x equals d z
i n t e g r a l space b e c o m e s
equals negative integral left parenthesis 1 plus z squared right parenthesis d z
equals negative open parentheses z plus z cubed over 3 close parentheses plus C
equals negative open parentheses c o t x plus fraction numerator c o t cubed x over denominator 3 end fraction close parentheses plus C
