What is the value of sin 2 90 degree?

For sin 2 degrees, the angle 2° lies between 0° and 90° (First Quadrant). Since sine function is positive in the first quadrant, thus sin 2° value = 0.0348994. . .

What is the sin value of 90?

1
The exact value of sin 90 degrees is equal to 1.

What is value of cos45?

The exact value of cos 45 degrees is 1/√2 (in surd form), which is also equal to sin 45 degrees. It is an irrational number, equal to 0.7071067812… in decimal form. The approximate value of cos 45 is equal to 0.7071.

How do you find the sin 90 Theta?

All triangles have 3 angles that add to 180 degrees. Therefore, if one angle is 90 degrees we can figure out Sin Theta = Cos (90 – Theta) and Cos Theta = Sin (90 – Theta).

How do you solve tan 90?

tan90∘ is undefined because you can’t divide 1 by nothing. Nothing multiplied by 0 will give an answer of 1 , so the answer is undefined.

What is the value of Cos 4pie?

What is the value of sin30 Cos 60?

Trigonometry Examples The exact value of sin(30) is 12 . The exact value of cos(60) is 12 .

What is the value of Sinsin 90?

Sin 90 degrees = 1 The angles are calculated with respect to sin, cos and tan functions which are the primary functions, whereas cosecant, secant and cot functions are derived from the primary functions. Usually, the degrees are considered as 0°, 30°, 45°, 60°, 90°, 180°, 270° and 360°.

What is the opposite of sin 90°?

For memorising cos 0°, cos 30°, cos 45°, cos 60° and cos 90° Cos is the opposite of sin. We should learn it like cos 0° = sin 90° = 1

What is sin 90 degrees equal to?

Start measuring the angles from the first quadrant and end up with 90° when it reaches the positive y-axis. Now the value of y becomes 1 since it touches the circumference of the circle. Therefore the value of y becomes 1. Therefore, sin 90 degree equals to the fractional value of 1/ 1. Some other trigonometric sine identities are as follows:
