1. [-/6.25 Points] DETAILS SALGTRIG4 7.5.001. MY NOTES ASK YOUR TEACHER We can use identities to help us solve trigonometric equations. Using a Pythagorean identity we see that the equation sin(x) + sin2(x) + cos?(x) = 1 is equivalent to the basic equation whose solutions are x = for any integer k. Need Help? Read It Submit Answer2. [-/6.25 Points] DETAILS SALGTRIG4 7.5.002. MY NOTES ASK YOUR TEACHER We can use identities to help us solve trigonometric equations. Using a Double-Angle Formula we see that the equation sin(x) + sin(2x) = 0 is equivalent to the equation Factoring we see that solving this equation is equivalent to solving the two basic equations sin(x) = 0 and Need Help?
