Question
what is your answer for 8sin^2theta + sintheta -1 ?
and how would you do it ? thanks
You have not written an equation. There is nothing to "solve". Did you leave out an " = 0 " ?
Yeah sorry
Yeah sorry
Let x = sin theta
8x^2 +x -1 = 0
x = [-1 +/- sqrt(33)]/16
= 0.296535 or -0.421535
theta = 17.250 degrees or -24.931 degrees
pork?
