How many degrees separate (cos and sin) maximum value?

So far, I know the maximum values are = 1 but don't know the degree of the maximum value...maybe I am thinking too hard. Please help.

Also, For what values of θ do the maximum and minimum occur ?

Presumably you know that sin(x)= 1 for and that sine has period . So for any integer k. Similarly, sin(x)= -1 for so for any integer k.

So how do I find out separate each maximum value ( above the pic is attach of the question)

I am assuming that you have graphed the two functions as required. I am GUESSING that the answers are to be given in radians.

Question a(iii) is one of those questions that are so absurdly easy that they confuse you. You say, "They must be asking something deeper than that."

$Let\ \theta_1\ be\ the\ value\ of\ \theta\ where\ cos(\theta )\ is\ maximum.\ So\ \theta_1 = what.$

$Let\ \theta_2\ be\ the\ value\ of\ \theta\ where\ sin(\theta )\ is\ maximum.\ So\ \theta_2 = what.$

The question is merely asking $\theta_2 - \theta_1 = what?$

The final question makes sense only if the overall question requires answers in radians. Otherwise the answer to what is the value of 50 degrees is 50 degrees.
