Spot the mistake then correct it.
Spot the source/start of the mistakes and say something about it.
S 2 sec² (æ)dæ
Given:
Step 1:
factor-out the coefficient 2 f sec2 (x) dx
Step 2:
let u
U =
find the du
da
Step 3:
du =
Step 4:
solve for dx
du
= dx
Step 5:
2 f sec? u
(승du)
substitute u and du
Step 6:
factor out
2 () S sec? udu
Step 7:
multiply 2 and
S sec? udu
recall: f sec? udu
= tan u +c
Step 8:
integrate
tan u + c
Step 9:
Substitute =
tan e +c
Final Answer
