sin(x)+sin(-(pi/2)x)
You asked:
Evaluate the expression: \(\sin\left( x \right) + \sin\left( -\left( \frac{\pi}{2} \cdot x \right) \right)\)
MathBot Answer:
\[\sin\left( x \right) + \sin\left( -\left( \frac{\pi}{2} \cdot x \right) \right) = \sin{\left(x \right)} - \sin{\left(\frac{x \pi}{2} \right)}\]
