Solve the Following Equations I have the answers here I need steps to solve each one, in order To get xtra credit. a) 4sin?+3?(3)=?(3)on the interval 0??<2? [4pi/3 and 5pi/3] b) Cos(2?- ? /2)=-1on the interval 0??<2? [3pi/4] c) 2sin^2?+3=5sin ? on the interval 0??<2? [pi/2] d) Sin^2 ?=2 cos? +2 on the interval 0??<2? [pi] Establish Identities and include how you arrived at answer a) 1+sin?/1-sin?=(sec?+tan?)^2 b) Tan^2?cos^2?+cot^2?sin^?=1 I will rate, please just give me a minute as I'm new at this

Explanation / Answer

1.4sin=- 23

sin=-3/2

=180+ 60=240

=360-60=300

2.Cos(2- /2)=-1

(2- /2)=2

=3/4
