pythagorean identity
Solve sin2(θ) – sin(θ) = 2 on the interval 0 ≤ θ < 2π
step 1:sin2(θ) – sin(θ) – 2 = 0
step 2:(sin(θ) – 2)(sin(θ) + 1) = 0
step 3:sin(θ) = 2
sin(θ) + 1 = 0
sin(θ) = –1
Answer:θ=3/2n
find the value of the cosine of an unspecified angle α, given that y=-7/25
step 1:x2+y2=1
step 2:x2+(−7/25) 2 =1
step 3:x2+49/625=1
step 4:x2=625/625-49/625
step 5:x2 =576/625=(24/25)2
cos=25/24
