Websin(x+y)sin(x−y) = 21[cos2y− cos2x] Explanation: We can use the product to sum formula sinAsinB = 21[cos(A− B)− cos(A+B)] ... First of all let's write sin(x− y) = sin(x)cos(y)−cos(x)sin(y) In order to have a better writing for the function: g(x,y) = sin(x)(1+ cos(y))+sin(y)(1−cos(x)) Now this is a ... y′ + sin(x +y) = sin(x− y ... WebExpress sin of sum of two angles in its ratio form The angle of Δ I C G is x + y. So, the sin of sum of two angles can be written in its ratio form from this triangle. sin ( x + y) = G I C G The side J F ― divides the side G I ― as …

WebJul 27, 2015 · Use logarithmic differentiation. y = (sinx)x lny = ln((sinx)x) = xln(sinx) (Use properties of ln) Differentiate implicitely: (Use the product rule and the chain ruel) 1 y dy dx = 1ln(sinx) + x[ 1 sinx cosx] So, we have: 1 y dy dx = ln(sinx) +xcotx Solve for dy dx by multiplying by y = (sinx)x, dy dx = (ln(sinx) + xcotx)(sinx)x Answer link WebIt is the same deal with sin and arcsin, which is conventionally written as sin^-1 x. Arcsin is the inverse of sin, such that arcsin (sin (x)) = x, or sin (arcsin (x))=x. It is important to know the inverse trig functions as they come in handy in many situations, like trig substitution in integral calculus.
