Sines and cosines are trigonometric identities
The corresponding match of the sine or cosine values are:
- Cos(57) = Sin(33)
- Sin(43) = Cos(47)
- Cos(43) = Sin(47)
- Sin(32) = Cos(58)
Given that:
Then:
This means that, angles a and b are opposite values
For cos(57),
The sine value is: sin(33)
This is so because:
57 + 33 = 90
When the above formula is applied to the remaining functions, we have:
sin(43) = cos(47)
cos(43) = sin(47)
sin(32) = cos(58)
