Step-by-step explanation:

Hope this helps!
W=-L+P/2
subtract L to the other side and then diving everything by 2 to get W by itself

Yas, I'm learning this
remember
f'(a+b)=f'(a)+f'(b)
and
f'(cos(x))=-sin(x)
and
f'(g(x))=f'(g(x))g'(x)
and
f'(xⁿ)=nxⁿ⁻¹
f'(a⁷+cos(7x))=
f'(a⁷)+f'(cos(7x))=
7a⁶+f'(cos(7x))f'(7x)=
7a⁶-sin(7x)(7f'(x))=
7a⁶-sin(7x)(7*1)=
7a⁶-sin(7x)(7)=
7a⁶-7sin(7x)
f'(a⁷+cos(7x))=7a⁶-7sin(7x)
