True or false
the value 3pi/2 is a solution for the equation 2sin^2x -sin x -1=0

False

Step-by-step explanation:

The given equation is:

Substituting x= in the above given equation, we have

=

=

=

=

Thus, the value of the given equation by substituting the value of x is equal to 2 and not zero, therefore the given statement is false.

- 1.613 = -1.6 or -1.61

-1.522 = -1.5 or -1.52

0.587 = 0.6 or 0.59

3.079 = 3.1 or 3.08
