How do you prove sin 45?
In a right triangle, one angle is, by definition, 90 degrees so the two acute angles sum to 180- 90= 90 degrees. To prove that sin(45 (degrees)) is 1√2 , consider that if a right triangle has one angle with measure 45 degrees then the other acute angle is 90- 45= 45 degrees also.
Why TAN 90 is infinity?
Here the angle is between a ray connecting the origin with the point (x,y) and the x-axis (positive angles measured counterclockwise). Using this method the tan of the angle is defined to be y/x. Since any angle having 90° will be on the y-axis, x will be zero. Division by zero is undefined therefore so is tan (90°).
What is equal to tan?
tan x = sin x cos x . The cotangent of x is defined to be the cosine of x divided by the sine of x: cot x = cos x sin x .
Is the value of sin 30?

What CSC 45?
The exact value of csc(45°) csc ( 45 ° ) is √2 .
How do you solve sin 45 without a calculator?
The hypothenuse AC can easily be calculated now: AC=√BC2+AB2=√12+12=√2 . The sine is defined as the ratio between the opposed side and the hypothenuse. Therefore, sin45o=1√2=√22 . In decimal form, it is roughly 0..

What is CSC?
The cosecant ( csc ) (\csc) (csc) The cosecant is the reciprocal of the sine. It is the ratio of the hypotenuse to the side opposite a given angle in a right triangle.
What is Cotangent math?
The short name for cotangent. It is the length of the adjacent side divided by the length of the side opposite the angle in a right-angled triangle. cot(θ) = adjacent / opposite. (Note: the tangent function tan(θ) = opposite / adjacent)
