For math, science, nutrition, history How about the following: Start with: sin(x) = cos(x) Divide both sides by cos(x) to get: sin(x)/cos(x) = cos(x)/cos(x) Recognize that sin(x)/cos(x) is tan(x) Recognize that cos(x)/cos(x) is unity So we have: sin(x)/cos(x) = tan(x) = 1 so x Free trigonometric equation calculator - solve trigonometric equations step-by-step Free trigonometric identities - list trigonometric identities by request step-by-step Tip: See my list of the Most Common Mistakes in English.It will teach you how to avoid mis­takes with com­mas, pre­pos­i­tions, ir­reg­u­lar verbs, and much more. The function $\sin(x)\cos(x)$ is one of the easiest functions to integrate. Solve for ? sin(x)=cos(x) Divide each term in the equation by .
