ExpertAnswers. hala718. | Certified Educator. (-sinx)^4 + (c0sx)^4 = 1. we know that sinx = -sinx. ==> (sinx)^4 + (cosx)^4 =1. Complete the square: ==> (sin^2 x + cos^2 x)^2 - 2sin^2 x cos*2 x =1
Solution To convert sin x + cos x into sine expression we will be making use of trigonometric identities. Using pythagorean identity, sin2x + cos2x = 1 So, cos2x = 1 - sin2x By taking square root on both the sides, cosx + sinx = sinx ± √1 - sin2x Using complement or cofunction identity, cosx = sinπ/2 - x sinx + cosx = sinx + sinπ/2 - x Thus, the expression for sin x + cos x in terms of sine is sin x + sin π/2 - x. What is sin x + cos x in terms of sine? Summary The expression for sin x + cos x in terms of sine is sin x + sin π/2 - x.
Findthe derivatives of functions that contain sin(x) or cos(x). For example, differentiate f(x)=2x+3sin(x).

Proofof cos(x): from the derivative of sine. This can be derived just like sin(x) was derived or more easily from the result of sin(x). Given: sin(x) = cos(x); Chain Rule. Solve: cos(x) = sin(x + PI/2) cos(x) = sin(x + PI/2) = sin(u) * (x + PI/2) (Set u = x + PI/2) = cos(u) * 1 = cos(x + PI/2) = -sin(x) Q.E.D.
sinx cos y = [sin(x - y) + sin(x + y)] / 2 cos x cos y = [cos(x - y) + cos(x + y)] / 2 Law of Sines: a /sin A = b /sin B = c /sin C Law of Cosines: a 2 = b 2 + c 2 - 2bc cos A If A = 90 degrees, then cos 90 = 0, and the equation reduces to the Pythagorean Theorem : a 2 = b 2 + c 2 :
Demostraciónde cos(x): desde la derivada de seno. Éste puede ser derivado como sin(x) fue derivado o mas fácilmente desde el resultado de sin(x). Dando: sin(x) = cos(x); La regla de la cadena. Resuelva: cos(x) = sin(x + PI/4) cos(x) = sin(x + PI/4) = sin(u) * (x + PI/4) (Fije u = x + PI/4) = cos(u) * 1 = cos(x + PI/4) = -sin(x) Q.E.D.
