How do you factor out a sin?
Solve 2sin3 x = sin x for all the possible angles in degrees.
- Move the term on the right to the left by subtracting it from each side.
- Factor out sin x.
- Set each factor equal to 0.
- Solve the two equations for the values of x that satisfy them.
- Take the square root of both sides of the quadratic equation and solve for x.
How do you factor identity?
When to Factor a Trigonometry Identity
- Factor sin x out of each term in the numerator.
- Replace the expression in the parentheses with its equivalent by using the Pythagorean identity.
- Now split up the fraction into a product of two fractions, carefully arranging the numerator and denominator.

Is there a problem with trig simplification?
Trig simplification can be a little tricky. You are given a statement and must simplify it to its simplest form. The problem is that sometimes you don’t even know where to begin. Your eyes are glued to the problem, your head begins to hurt, and you keep writing the same equation over and over.
How to simplify an expression in Symbolic Math Toolbox?
See Choose Function to Rearrange Expression. Besides specific simplifiers, Symbolic Math Toolbox™ offers a general simplifier, simplify. If you do not need a particular form of expressions (expanded, factored, or expressed in particular terms), use simplify to shorten mathematical expressions.
How to simplify expressions in MATLAB and Simulink?
Simplify expressions involving trigonometric functions. Simplify expressions involving exponents and logarithms. In the third expression, use log (sym (3)) instead of log (3) . If you use log (3), then MATLAB ® calculates log (3) with the double precision, and then converts the result to a symbolic number.
