## Is sinx COSX 1 an identity?

Because sin(2x)u22641 for all xu2208R (for all real-valued x ) that means that cos(x)sin(x)u226412 for all real x .

## What is the solution of sinx COSX 1?

The general solution of the trigonometric equation sin x+cos x 1 is given by: (1) x 2nu03c0; n0, xb11, xb12

## What is Sinx plus COSX?

Answer : The expression for sin x + cos x in terms of sine is sin x + sin (u03c0 / 2 x).

## What is the relationship between Sinx and COSX?

sin(x) is related to cos(x) simply by increasing the argument of either function (x) by Pi/2 radians.

## How do you solve Sinx plus COSX?

From the unit circle we see that sin x and cos x can only have the same value in two places, in x /4 and x 5 /4 (45xb0 and 225xb0). The equation sin x cos x can also be solved by dividing through by cos x. If we put k 0 and k 1 we get the solutions /4 (45xb0) and /4 + 5 /4 (45xb0+ 180xb0 225xb0).

## What is sinx * COSX equal to?

The tangent of x is defined to be its sine divided by its cosine: tan x sin x cos x .

## What is COSX plus sinx?
