What is the Value of Cos 5pi/2?

Answer: cos(5π/2) is equal to 0.

Explanation:

Note that 5π/2 can be written as follows.

$\dfrac{5\pi}{2}=2\pi +\dfrac{\pi}{2}$.

Now using the formula cos(2π+θ)=cosθ, we obtain that

$\cos(\dfrac{5\pi}{2})=\cos(2\pi +\dfrac{\pi}{2})$.

= $\cos \dfrac{\pi}{2}$

= 0.

So the value of cos 5pi/2 is equal to 0.

By the rule cos(-θ) = cosθ, we have that

cos(-5π/2) = cos(5π/2) = 0, by the above.

∴ cos(-5π/2) = 0.

Therefore, the value of cos(-5pi/2) is equal to 0.
