sin 90 degrees

Let us learn about sin 90 degrees

sin90°, sinα = y/x, 90° angle is known as a right angle y =1 r= 1 x = 0

sin 90° = y/r = 1/1 = 1

By the meaning in trigonometry, sin x = opposite/hypotenuse

Where “x” indicates any degree. In this case the x is 90⁰ that are we need to get the value of sin ninety degrees. Hence we need to draw the right angled triangle.

· A right angled triangle opposite side’s length is equal to hypotenuse side length.

· the sine of the angle = The length of the opposite side is divided by Hypotenuse length

Finally sin 90⁰ = the length of the ‘hypotenuse side’ is divided by The length of the ‘hypotenuse side’

= 1.

· The normal outline of sin can be mention as sin X = cos(90-X), hence sin 90 = cos (90-90) = cos 0 =1
