I'm trying to make a function in C that returns the length of the side of a triangle that is opposite to a given angle, using the Law of cosines. Now I got the formula to work in excel and it gave the correct results. However when I tried it in C I am getting the wrong results, and I can not work out why.

Since expressions for sin 15° and cos 15° can be found by using the difference formulas for sine and cosine (with 15° = 45° - 30°), the expressions for sin 18° and cos 18° can then be used again with the difference formulas to get sin 3° and cos 3°, and hence the trigonometric functions of any integer multiple of 3°.

For triangles labeled as in Figure 3, with angles [latex]\alpha ,\beta [/latex], and [latex]\gamma [/latex], and opposite corresponding sides [latex]a,b[/latex], and [latex]c[/latex], respectively, the Law of Cosines is given as three equations. Since expressions for sin 15° and cos 15° can be found by using the difference formulas for sine and cosine (with 15° = 45° - 30°), the expressions for sin 18° and cos 18° can then be used again with the difference formulas to get sin 3° and cos 3°, and hence the trigonometric functions of any integer multiple of 3°.

Dec 22, 2020 · I'm having some trouble with basic trigonometry and I'm trying to understand it better. So I apologize in advance if I'm doing some obvious mistake. Now lets say I have: cos(x)cos(y)+sin(x)sin(y)=z. Using difference formula for cosine I can write it as: cos(x-y)=z. But, can I also write that: cos(y-x)=z ?
