In the illustration below, sin(α) = a/c and sin(β) = b/c. Expand: sin^2x=1-cos2x-sin^2x 5.senisoc rof alumrof elgna elbuod eht fo eno esu . Solution. Jokes apart, sin4(x) = (1 − cos2(x))2 = (1 − cos(2x) 2)2 = 1 4 − cos(2x) 2 + cos2(2x) 4 hence: sin4(x) = 3 8 − cos(2x) 2 + cos(4x) 8 = 3 − 4cos(2x) + cos(4x) 8. 1 − sin ( x) 2 csc ( x) 2 − 1. Hope this helps.
sin4(x) = (sin4x)1. The degree cannot be determined because sin(θ)− 4 5 sin ( θ) - 4 5 is not a polynomial. From geometry, this turns out to be a 3-4-5 right triangle, hence cosA=3/5.)x2soc-1(2/1 =x2^nis gnivael ,2 yb sedis htob ediviD . Substitute cos2x+sin^2x into sin^2x=1-cos^2x for cos^2x 4. cosx =3/5 or -3/5, cosx = + or - sqr (1-sin^2x) = sqr (1-16/25) = sqr (9/25 = 3/5. Tap for more steps csc(x) = − 5 4 csc ( x) = - 5 4 This is the solution to each trig value. it's negative because 2x is in quadrant II or III where cosines are negative. sin(t) = sin(α) and cos(t) = − cos(α) sin(t) = − sin(β) and cos(t) = cos(β) Figure 16. Question. Hence, I = ∫ 01/6 1−9x2dx = ∫ 0π/6 1−sin2(θ) 3cos(θ)dθ
Example 5. Use the definition of sine to find the known sides of the unit circle right triangle. The exact value of is . sin(θ)− 4 5 = 0 sin ( θ) - 4 5 = 0.
