Question

What is the minimum and maximum value of sin theta and cos theta

Answer 1

the minimum value of cos theta 0
maximum values 1
minimum values of sin theta -1 then maximum values of sin theta + 1

Answer 2

The minimum and maximum value of the sin∅ and cos∅ is -1 and +1.

1) By the curve of the sin∅ it is very clear that the value of the x is positive for one cycle and negative for the other cycle.

2) The range of that cycle of sin∅ is from-1 to +1.

3) Again it is very clear by the curve of the cos∅ that the value of the x is positive for one cycle and negative for the other cycle.

4) The range of that cycle of cso∅ is also from-1 to +1.
