Re: Various Trig Problems

Have you read your textbook or tried any of these problems?

To find the x-intercept, set x=0 and solve for y.

To find the y-intercept, set y=0 and solve for x (you may get multiple solutions).

Q 5. Compare The expression with the standard from i.e., f(x) = A sin ( Bx + C ) + D the phase shift is given by C. In this case the phase shift is pi/2

Q 6. arcsin(-(sqrt3)/2) that means we want to find that angle for which sin has the value -(-(sqrt3)/2).

We have learnt that Sinθ = √3/2 for θ= π/3 and also trigonometric ratio sine is negative in 3rd and 4th Quadrant.

Therefore Sinθ = - √3/2 for θ = π+ π/3= 4π/3 and 2π- π/3= 5π/3.
