Question

Please help me get started on find the following integral. click to see

Answer 1

\[\int\limits_{}^{}\sin ^{3}(x)dx\]

Answer 2

try this...
\(\large \int\limits_{}^{}\sin ^{3}(x)dx = \int\limits_{}^{} sin(x) \cdot \sin ^{2}(x)dx \)
= \(\large \int\limits_{}^{} sinx \cdot (1-cos^2x)dx \)

now do a u-substitution where u=cosx

Answer 3

ok ill try that out, thanks...

Answer 4

yw...:)

Answer 5

you can also try sin3x=3sinx-4sin^3 x
4sin^3 x=3sinx-sin3x
