Using the graph, determine the values of `theta`, for which `sin theta` and `tantheta` increases together for `0 le 0 le pi`.

Explanation

In the first quadrant, `sin theta` increases from 0 to 1 and in the second quadrant, `sin theta` decreases from 1 to 0. While `tan theta`, in the first quadrant, increases from 0 to `infty` and in the second quadrant, it increases from `-infty` to 0.
Thus, in the first quadrant `(0 le theta le pi/2)`, both `sin theta` and `tan theta` increases together.
