I think this is not right.

GTFO with your high school kiddie shit, read the sticky

But there is no explanation as to why mgcosθsinθ doesn't work.

Nigga you got components that aren't parallel. Do you even know what a fucking axis is?

The tick marks indicate equal forces, not paralleliness.

[eqn]
\begin{aligned}
\int \frac{\cos(\sqrt{x})}{\sqrt{x}} \; dx &= \int 2\cos{u} \; du \quad \quad u = x^{\frac{1}{2}} \; \; 2du = \frac{1}{\sqrt{x}} \, dx \\
&= 2 \sin{u}+C \\
&= 2 \sin{\sqrt{x}}+C
\end{aligned}
[/eqn]

If you set up y-axis like that then you have to include the y component of Fe
