The expression that completes the identity ( \sin u \cos v ) is ( \frac{1}{2} (\sin(u + v) - \sin(u - v)) ). This identity is derived from the product-to-sum formulas in trigonometry, which relate products of sine and cosine functions to sums and differences of sine functions.
The expression ( \sin(72^\circ - a) ) can be rewritten using the sine difference identity: [ \sin(72^\circ - a) = \sin(72^\circ) \cos(a) - \cos(72^\circ) \sin(a). ] Thus, ( \sin(72^\circ - a) ) is equal to ( \sin(72^\circ) \cos(a) - \cos(72^\circ) \sin(a) ).
The expression (\sin^2(x)) (read as "sine squared of x") is equal to ((\sin(x))^2), meaning it represents the square of the sine of the angle (x). This value can vary between 0 and 1, depending on the angle (x). Additionally, it can be expressed using the Pythagorean identity as (\sin^2(x) = 1 - \cos^2(x)).
Sin(42 o ) = 0.669130606 = 0.6691 ( 4 d.p._.
YES!!!! Sin(2x) = Sin(x+x') Sin(x+x') = SinxCosx' + CosxSinx' I have put a 'dash' on an 'x' only to show its position in the identity. Both x & x' carry the same value. Hence SinxCosx' + CosxSinx' = Sinx Cos x + Sinx'Cosx => 2SinxCosx
The expression (\sin(3\alpha)) can be expanded using the triple angle formula for sine, which is (\sin(3\alpha) = 3\sin(\alpha) - 4\sin^3(\alpha)). This formula allows you to express (\sin(3\alpha)) in terms of (\sin(\alpha)).

You cannot. sin(n)/n is an expression, not an equation. An expression cannot be solved.
The identity for tan(theta) is sin(theta)/cos(theta).
sin[cos-1(x)] is an expression; it is not an equation (nor inequality). An expression cannot be solved.
Sine sum identity: sin (x + y) = (sin x)(cos y) + (cos x)(sin y)Sine difference identity: sin (x - y) = (sin x)(cos y) - (cos x)(sin y)Cosine sum identity: cos (x + y) = (cos x)(cos y) - (sin x)(sin y)Cosine difference identity: cos (x - y) = (cos x)(cos y) + (sin x)(sin y)Tangent sum identity: tan (x + y) = [(tan x) + (tan y)]/[1 - (tan x)(tan y)]Tangent difference identity: tan (x - y) = [(tan x) - (tan y)]/[1 + (tan x)(tan y)]
cos(x) = sin(pi/2 + x)
90+ whatever number is in form of sin.
It is a mathematical expression.
sec x - cos x = (sin x)(tan x) 1/cos x - cos x = Cofunction Identity, sec x = 1/cos x. (1-cos^2 x)/cos x = Subtract the fractions. (sin^2 x)/cos x = Pythagorean Identity, 1-cos^2 x = sin^2 x. sin x (sin x)/(cos x) = Factor out sin x. (sin x)(tan x) = (sin x)(tan x) Cofunction Identity, (sin x)/(cos x) = tan x.
You use the identity sin2x + cos2x = 1 (to simplify the expression in parentheses), and convert all functions to sines and cosines. sec x tan x (1 - sin2x) = (1/cos x) (sin x / cos x) (cos2x) = (sin x / cos2x) cos2x = sin x
An identity is a statement which says two quantities are equal, like as x + y = y + x or sin (x + y ) = sin x cos y + cos x sin y .
The expression (\sin^2(x)) (read as "sine squared of x") is equal to ((\sin(x))^2), meaning it represents the square of the sine of the angle (x). This value can vary between 0 and 1, depending on the angle (x). Additionally, it can be expressed using the Pythagorean identity as (\sin^2(x) = 1 - \cos^2(x)).
