simplify-6picos(120pit+pi/2)

simplify

- 6 π cos (120 π t + \frac{π}{2})

6 π sin (120 π t)

Solution steps

- 6 π cos (120 π t + \frac{π}{2})

Rewrite using trig identities

= - 6 π (- sin (120 π t))

Apply rule

- (- a) = a

= 6 π sin (120 π t)

sin (x + nπ)

sin (+ arcsin (t))

sin (\frac{π}{2} + 2 π x)

- cos (\cdot (- cos (x)))

2 sin ((\frac{π}{3}) - 2 x) + 3
