Draw a right triangle ABC, with m(CAB)=∅.
Let CB=7 units, AC=8 units, so by the Pythagorean theorem:
(units)
so we have drawn a triangle where sin∅=7/8
in this triangle, cot∅=(adjacent side)/(opposite side)=

The answer is below
Step-by-step explanation:
When you refer to a normal vector you mean the form a*x + b*y + c*z = d, if that's the case then it's not unique in the nose because it gives you its normal vector. Taking into account that uniqueness only supports multiplicative constants, which means that you can multiply the equation with whatever you want, that is, it remains the same
Step-by-step explanation:
We know that
cos 2x = 2cos²x - 1
So we have
Substituting
