Answer:
-(23/6)π
-(19/6)π
-3π
Step-by-step explanation:
cos2t=cos^2t-sin^2t => cos^2t=1-sin^2t =>cos2t=1-2sin^2t
sint=1-2sin^2t, if x=sint, thenn we have 2x^2+x-1=0
Here x=0.5, x=-1, as x=sint => sint = -1 solutions for -4π to -2π is t=-3π,
sint = 0.5 solutions for -4π to -2π is t= -(23/6)*π, and t = -(19/6)*π
Answer:
46.66%
Step-by-step explanation:
42/90 = x/100
find x
multiply 42 times 100 and divide by 90
Answer:
x=51.9
Step-by-step explanation:
sin x = 7.4/9.4
sin x= 0.787
sin^-1(0.787)=x
x=51.9
