Question

if the point a (pi/6,-2) lies on the graph of f(x)
=sin(x+pi)-d then the value of d is?

Answer 1

So you have y = sin ( x + pi) - d. Now plug in your point and solve for d.
- 2 = sin (pi/6 + pi) - d
-2 = sin 7pi/6 - d
d = 3/2

Answer 2

isint pi over six plus pi equal to 2 pi over 6

Answer 3

nvm i got it thanks\
