Cos 45 degrees equals sin?
cos(45) = sin(45) You can see this as follows: imagine a circle with radius 1. The point on the circle with angle 45 degrees, lies on the line y=x, equally far from the x-axis (cos) as the y-axis (sin). The angle for both must be 45, because x and y are orthogonal: 90 deg, so if the angle with x is 45, then the angle with y must be 90-45=45. So: for this point, both angles are 45, and the distance to x (cos) is equal to the distance to y (sin). Therefore, cos(45) = sin(45). Additionally, cos(45) = sin(45+90) = sin(45+360n) = sin(135+360n) with n integer.

Does tan 45 degrees and sin 45 degrees equal trig values?
They are both trig values, but not equal. Tan 45 is 1 and sin 45 is 0.7071
If angle A is 60 degrees angle B is 45 degrees angle C is 75 degrees and the length of side AC is 10 units then what is the length of side AB?
This problem can be solved using the Sine Rule :a/sin A = b/sin B = c/sin C 10/sin 45 = AB/sin 75 : AB = 10sin 75 ÷ sin 45 = 13.66 units (2dp)
Find out value of sin 45 cos 45 - sin 230?
Assuming that the angles are all stated in degrees: sin(45) = cos(45) = 1/2 sqrt(2) sin(45) cos(45) = (1/2)2 x (2) = 1/2 sin(230) = - 0.7660444 sin(45) cos(45) - sin(230) = 0.5 + 0.7660444 = 1.2660444 (rounded)
What is the arc-sin of 45 degrees?
The arc-sine (or inverse sine) of 45 degrees is the angle whose sine value is equal to the sine of 45 degrees. Since the sine of 45 degrees is ( \frac{\sqrt{2}}{2} ), the arc-sine of ( \frac{\sqrt{2}}{2} ) is 45 degrees. Therefore, the arc-sin of 45 degrees is also 45 degrees, given that it falls within the principal range of the inverse sine function.

What is the cot of a 45 degree angle?
1 cot(theta)=cos(theta)/sin(theta) cos(45 degrees)=sqrt(2)/2 AND sin(45 degrees)=sqrt(2)/2 cot(45 deg)=cos(45 deg)/sin(deg)=(sqrt(2)/2)/(sqrt(2)/2)=1
Find out value of sin 45?
The value of sin 45 degrees, or sin(π/4 radians), is √2/2. This is derived from the properties of a 45-45-90 triangle, where the lengths of the legs are equal. Therefore, sin 45° represents the ratio of the opposite side to the hypotenuse in this triangle configuration.
What if the sine of an angle is 0.707 what is value of that angle in degrees?
sin-1(0.707) = 44.99134834 or about 45 degrees

How do you solve sin x plus cos x equals zero?
The statement of the problem is equivalent to sin x = - cos x. This is true for x = 135 degrees and x = -45 degrees, and also for (135 + 180n) degrees, where n is any integer.
What is the sin theta of 45 degrees?
The sine of 45 degrees is equal to (\frac{\sqrt{2}}{2}). This value arises from the properties of a 45-45-90 triangle, where both legs are equal and the hypotenuse is (\sqrt{2}) times the length of each leg. Consequently, the sine function, which is defined as the ratio of the opposite side to the hypotenuse, yields this result for 45 degrees.
Is the cosine sine and tangent of an angle equal to each other?
No; those could be three different values, or sometimes two of them might be the same. For example, if the angle is 45 degrees, the values are about... cos:0.707 sin: 0.707 tan: 1 For 45 degrees, the cosine and sine are the same. For 36 degrees, cos:0.809 sin: 0.588 tan: .727
