simplify cos(x)-cos(x+pi/2)

simplify

cos (x) - cos (x + \frac{π}{2})

cos (x) + sin (x)

Solution steps

cos (x) - cos (x + \frac{π}{2})

Rewrite using trig identities

= cos (x) - (- sin (x))

Apply rule

- (- a) = a

= cos (x) + sin (x)

sin (2 π x) + sin (2 π x - π)

12 A \cdot sin (850 \cdot t - 0.23)

sec (18 0^{\circ} + θ)

- cos (x + π) + cos (x)

2 tan^{2} (x) + 2

What is cos(x)-cos(x+pi/2) ?
The solution to cos(x)-cos(x+pi/2) is cos(x)+sin(x)
