Question

sin2(x) - sin (x) +1 = 0

Answer 1

sin squared, correct? And completely agree with the name, btw, haha. I'll take calc over trig any day -_-

Answer 2

Yes

Answer 3

You're actually going to have no solution for this one. For these you have to pretend that sinx = just plain old x. If you do so you get:

\[x ^{2}-x + 1 = 0\]

You would try to factor that qith quadratic formula and, at the end, relace x with sinx. But you'll see when you try the quadratic formula, you'll come up with imaginary numbers.

Answer 4

Its asking to use the trig identities to solve for this question, the using to unit circle to find the answer. The example for the question before was taking sin x = cos x -> which then converts to tan x = 1, after dividing by cos x and relating it to tan x = sin x / cos x. Then finding the parts on the unit circle that have tan= 1 which would be pi/4, and 5pi/4....
there is no real good explanation for what the question is asking

Answer 5

I wish I could say that made any sense. I can tell you for certain there is no solution. If you tried identities, you might be running around in circles all day. This just simply isn't an identity question, it's a quadratic equation in sinx.
