How can logarithms help solve an equation involving trigonometric functions?

In summary, Trigonometry is a branch of mathematics that studies triangles and their relationships. The three basic trigonometric functions are sine, cosine, and tangent, which represent ratios of sides in a right triangle. Logarithms are the inverse of exponential functions and are used to solve equations and represent large numbers. Trigonometry and logarithms are related through the unit circle, and they have many practical applications in fields such as engineering, physics, navigation, and everyday situations like measuring heights and distances.

4[tex]^{sinx}[/tex] = [tex]\sqrt[cosx]{2}[/tex]

I use logarithmic and i get :

sinx * log(4) = (1/cosx) * log(2)

sinx*cosx = log(2)/log(4)


what should i do next?

What is log(2)/log(4)? Try applying a change of base rule. Afterward, see if you can use any of your trigonometric formulas to simplify.
