What is the formula for finding the angle of an triangle using law of cosines?
a2 = b2 + c2 - 2bc cos(alpha) b2 = a2 + c2 - 2ac cos(beta) c2 = a2 + b2 - 2ab cos(gamma) There are all three formulas. Do not forget to use, arc-cos, when finding angles.
Csc x tan x?
If you want to simplify that, it usually helps to express all the trigonometric functions in terms of sines and cosines.
How do you simplify tan ( - x ) cos ( - x )?
It helps, in this type of problem, to convert all trigonometric functions to sines and cosines. As a reminder, tan(x) = sin(x) / cos(x).
Is 1 plus sinX divided by 1 plus cscX equal to sinX?
2
What is cot x sin x simplified?
To simplify such expressions, it helps to express all trigonometric functions in terms of sines and cosines. That is, convert tan, cot, sec or csc to their equivalent in terms of sin and cos.
Are direct cosines of a vector unique?
No, the direct cosines of a vector are unique only up to a sign change. This means that if a set of direct cosines uniquely defines a vector, a set of direct cosines with opposite signs for all components would define the same vector.
Can The law of cosines can only be applied to acute triangles?
No, it applies to all triangles.
Can law of cosines can only be applied to acute triangles?
No, it applies to all triangles.
