Help super urgent maths

Helppp…
Why is the maximum occurring when it’s equal to pi over 2??
Isn’t it when the
Sin(angle) is one like in the first part he multiplied 25 by one to get the max value

Maximum of

R \sin(\theta - \alpha)

occurs when

\sin(\theta - \alpha)=1

.

Which means

\theta - \alpha = \pi/2

which means

\theta = \pi/2 + \alpha

.

Wry side observation: I see you've moved up to "super urgent".
