# How do you evaluate sin((3pi)/2)?
We have to find the value of sin (3∏/2)
### Solution
sin (3∏/2)
We know that ∏ = 180 degrees
3∏/2 = (3 X 180)/2 = 270
sin 270 can be found using 90 degrees
sin 270= sin(3×90 +0 )
sin(270)=sin(3×90 +0 )
We know that
sin (90° + θ) = cos θ
sin(270)=−cos0
sin(270)=−1.

The quadratic 2x^2 - 6x + 8 can be written in the form a(x + b)^2 + c, where a, b, c and are constants. What is a + b + c?
May 20, 2022
$$2x^2 - 6x + 8 = 2(x^2 - 3x) + 8=2\left(x^2 - 3x + \dfrac94\right) +\dfrac72 = 2\left(x - \dfrac32\right)^2 + \dfrac72$$ | HuggingFaceTB/finemath | |
