I got this expression:
a / ( a2*sin(t)2 + cos(t)2 )
Is there any way to reduce it using some identity?
a / ( a2*sin(t)2 + cos(t)2 )
Is there any way to reduce it using some identity?

sjb-2812 said:What is sin(t)2 + cos(t)2 ?
Char. Limit said:Does that really matter, though? We're not dealing with sin^2(t)+cos^2(t). We're dealing with (a sin(t))^2 + cos^2(t).
sjb-2812 said:True, just trying a few things. Can we factor the bottom to give (sin2t + cos2t) x something? Might be useful, might not
Reducing an expression involves simplifying it to its simplest form. It makes the expression easier to work with and can help to reveal relationships between different variables.
In this expression, a2 is a common term in both the numerator and denominator. Dividing by this term helps to eliminate it and simplify the expression.
No, this expression is already reduced to its simplest form. All common terms have been eliminated and the expression cannot be simplified any further.
The trigonometric functions, sin and cos, represent the relationship between sides and angles in a right triangle. In this expression, they are used to represent the relationships between different variables.
Reducing an expression can help to simplify complex equations and make them easier to solve. This can be useful in many fields, such as engineering, physics, and finance, where complex calculations are often required.
