The trick to solve trig identities is intuition, which can only be gained through experience, tricks to solve trigonometry problems. The more basic formulas you have memorized, the faster you will be. The following identities are essential to all your work with trig functions, tricks to solve trigonometry problems.

Make a point of memorizing them. Quotient Identities :. Reciprocal Identities :. Pythagorean Identities:. For a list of other important identities, see the Trig Cheat Sheet article in this series. The following seven step process will work every time. It is rather tedious, and can take more time than necessary. As you gain more practice, you can skip or combine these steps when you recognize other identities. STEP 1: Convert all sec, csc, cot, and tan to sin and cos.

Most of this can be done using the quotient and reciprocal identities. STEP 2: Check all the angles for sums and differences and use the appropriate identities to remove them.

STEP 3: Check for angle multiples and remove them using the appropriate formulas. STEP 4: Expand any equations you can, combine like terms, and simplify the equations, tricks to solve trigonometry problems. STEP 6: Factor numerators and denominators, then cancel any common factors. STEP 7: Now, both sides should be exactly equal, or obviously equal, and you have proven your identity.

STEP 1: Everything is already in sin and cos, so this part is done. STEP 2: Since there are no sums or difference inside the angles, this part is done. STEP 3: cos 2x is a double angle. STEP 4: Here is where your algebra knowledge comes in. Now, our problem looks like this:.

The sides are almost the same. STEP 5: There are no powers greater than 2, so we can skip this tricks to solve trigonometry problems. STEP 6: Since cos 2 x — sin 2 x appears on both sides of the equation, we can cancel it.

STEP 7: Since this is one of the Pythagorean identities, we know it is true, and the problem is done. The 7 step method works both sides and meets in the middle, like a V, tricks to solve trigonometry problems. Some teachers will ask you to prove the identity directly from one side to the other in a straight line.

That is easily done using the work above. Just write down all the left side parts in order first, then the right side parts in backwards order, so it looks like this:. Or write the right hand steps in order first and then the left hand step backwards so it looks like this:.

Even though this is a simple problem, the same steps will work every time to solve trig identities no matter the difficulty. Continue reading below for additional help on how to solve trig identities! Bright Hub Education. Skip to content. Essential Identities The trick to solve trig identities is intuition, which can only be gained through experience.

Solving trig identities takes practice! How to Solve Trig Identities The following seven step process will work every time. Proving Trigonometric Tricks to solve trigonometry problems The 7 step method works both sides and meets in the middle, like a V.

Extra Tips Get both sides of the equation in the same functions. Once you get the hang of it, you will begin to see patterns. For instance, in tricks to solve trigonometry problems example above, you might notice right off that the left side is difference of two squares and do that first. If you keep getting stuck on a problem, take a break. Come back with a clean sheet of paper, and start over from the beginning.

Often, it helps to change the direction from left-right to right-left. Let someone else read through your work, just to see if they follow it and can give a new perspective.
