Answer:
sin2θ - cos2θ = 2sin² θ
Step-by-step explanation:
hello :
tan θ = 1 means : sinθ /cosθ so : sinθ =cosθ
sin2θ = 2sin θ cosθ =2sin² θ
cos2θ = cos²θ - sin²θ = sin²θ - sin²θ =0
sin2θ - cos2θ = 2sin² θ
A) x2+y2=z2
B)g2+f2=h2
C)t2+s2=r2
Formula is set to be (leg)2+(leg)2=(hypothenus)2 hypothenus is always the side opposite the right angle
Answer:
0.3212, 0.332, 0.340, 0.3412, 0.342, 0.348, 0.35, 0.352
Step-by-step explanation:
the value of x will be 920
Just sub x in with 5.
So 6(5)^3+8(5) = 6 (125) + 40 = 750 + 40 = 790.
So 790
