Find the values of angle a for which the following is true sin a=0 and cot= -1

A=0 and π

Step-by-step explanation:

It is given that and , we have to find the value of angle A for which   and is true.

Thus,

⇒

⇒

Thus, if   then .

And  

⇒

⇒

Thus, if , then .

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .
