The equation is:

cotg(X) = (sqrt(3)*cos(50º) + sin(50º))*(1-2*sqrt(3)*cos(50º)+2*sin(50º)) /

(sqrt(3)*sin(50º) - cos(50º))

Using a calculator, I find X = 50º.

How to develop the equation to find the solution?

Thanks.

What do you mean by "develop" the equation? The right side is simply a number. Find that number and take its inverse cotangent.

Doing what you propose with the calculator we arrive to 50 degrees.

So, if X = 50, it would be possible to "develop" or simplify the trigonometric expression on the second member of the equation to arrive to cotg(50).

Don't you think so, considering that in the expression we have only trigonometric functions of the same angle? - December 21st 2011, 10:59 AMFernandoRevillaRe: How to solve an equation
