The best way to verify trigonometric identities is to follow these general steps:
- Start with one side of the identity that you want to prove.
- Use known trigonometric identities and algebraic techniques to manipulate the expression on that side of the equation.
- Simplify the expression as much as possible.
- Continue manipulating and simplifying until you arrive at the other side of the identity.
Here are some common techniques and identities that can be helpful:
- Basic trigonometric identities: These include Pythagorean identities (sin^2(x) + cos^2(x) = 1), reciprocal identities (csc(x) = 1/sin(x), sec(x) = 1/cos(x), cot(x) = 1/tan(x)), and quotient identities (tan(x) = sin(x)/cos(x)).

- Sum and difference identities: These allow you to express trigonometric functions of the sum or difference of angles in terms of trigonometric functions of the individual angles. For example, sin(x + y) = sin(x)cos(y) + cos(x)sin(y).
- Double-angle and half-angle identities: These can be useful for simplifying expressions involving trigonometric functions of angles that are twice or half of each other. For example, sin(2x) = 2sin(x)cos(x).
- Trigonometric Pythagorean identities: These involve trigonometric functions squared and can help simplify expressions. For example, 1 – tan^2(x) = sec^2(x).
- Trigonometric function properties: Keep in mind properties like even/odd functions (e.g., sin(-x) = -sin(x), cos(-x) = cos(x)), periodicity (e.g., sin(x + 2πn) = sin(x)), and co-function identities (e.g., sin(π/2 – x) = cos(x)).
- Substitution: Sometimes, substituting a trigonometric identity or variable substitution (e.g., letting u = sin(x)) can make the identity easier to work with.
- Common algebraic manipulations: Factor, expand, combine like terms, and use algebraic techniques as needed to simplify expressions.
Remember to be patient and methodical when verifying trigonometric identities. It may take several steps, and you may need to try different approaches to reach the desired result. Practice and familiarity with trigonometric identities will improve your skills in this area.

Howdy just wanted to give you a quick heads up. The words
in your post seem to be running off the screen in Internet explorer.
I’m not sure if this is a format issue or something to do with browser compatibility but I figured I’d post to let you know.
The design and style look great though! Hope you
get the problem fixed soon. Cheers
