🏐 What Is Cos X Divided By Sin X

Thecorrect option is A1 2Explanation for the correct option:Step 1: Find the value of yGiven,y = c o t - 1 1 + sin x + 1 - sin x 1 + sin x - 1 - sin xOn rationalization the function,y = c o t - 1 ( 1 + sin x) + ( 1 - sin x) 2 ( 1 + sin x) - ( 1 - sin x) = c o t - 1 ( 1 + sin x) + ( 1 - sin x) + 2 ( 1 - sin 2 x) ( 1 + sin x - 1

. Use the known trigonometric identity. cos(a + b) = cosa ⋅ cosb −sina ⋅ sinb. we have that. cos(x + π 2) = cosx ⋅ cos( π 2) − sinx ⋅ sin( π 2) = cosx ⋅ 0 −sinx ⋅ 1 = − sinx. Finally. cos(x + π 2) = − sinx. Answer link. Use the known trigonometric identity cos (a+b)=cosa*cosb-sina*sinb we have that cos (x

Neithersine nor cosine can ever exceed 1 and the closer one of them is to 1, the closer the other must be to 0. We can see this in two ways: It follows immediately from the formula. As either sine squared or cosine squared gets closer to one the amount left for the other diminishes. It can be seen from the geometry.

LHS : sin (x − y) sin (x + y) = sin x cos y − cos x sin y sin x cos y + cos x sin y = cos x cos y sin x cos y Recallthe definition of cosine, sine and tangent. Cosine theta equals x, sine theta equals y and tangent theta equals y over x, where x and y are the coordinates of the point on the terminal side of the angle. And the 3 new functions are secant theta, cosecant theta and cotangent theta. Secant theta is defined as 1 over x.
