They are both trig values, but not equal. Tan 45 is 1 and sin 45 is 0.7071
cosine 45° = √2/2 (Square root of 2 over 2)

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
√ 1/2 = sine(45)= cosine(45) -Key
The vapor pressure of propanone (acetone) at 45 degrees Celsius is approximately 365 mmHg according to reference table h.
The sine and cosine of acute angles are equal only for 45° sin45° = cos 45° = 1/sqrt(2) = 0.7071
45 degree
cos(495) = cos(495-360) = cos(135) = -cos(180-135) = -cos(45) = -sqrt(1/2) or -1/sqrt(2)
135 degrees is the supplement of 45 degrees. When you minus 45 degrees from 180 degrees you will get 135 degrees which is the supplement angle of 45 degrees.
To minimize work, the angle between force and displacement should be 90 degrees (perpendicular). This is because work done is calculated as the dot product of force and displacement vectors, and the cosine of 90 degrees is 0, resulting in zero work. To maximize work, the angle should be 0 degrees (parallel), as the cosine of 0 degrees is 1, resulting in maximum work done.
They are: 90 degrees, 45 degrees and 45 degrees
