Question

If f(x)=2sinx^2x+sinx+1, find the value of f(π/6)
1.3/2
2. 2
3.5/2
4.5+- radical 3/2

Answer 1

Plug in pi/6 and solve.

Answer 2

it can be converted into degree by multiplying by 180 degree / pi

Answer 3

so pi / 6 * 180 / pi = 30 degree now put 30 degree and solve it by putting values

Answer 4

f(30) = 2sin^2 30degree + sin 30 degree + 1
= 1/2+1/2 +1
= 2
