You can put this solution on YOUR website! you change everything to sin and cos .. so what u do is you prove the left side since it will be easier
since in the first term we have the same denominator they can be one fraction
so it will be
now we just multiply the two terms
now we know when we have two terms being multiplied and the sign is different we will have something like this
same thing applies for the numerator in this equation
and we also know the trigonometric identity that says
so we substitute that in for the numerator also and we get
dividing two same number with different exponents means subtracting the exponent so we will end up with
note : it is supposed to be the sin that is squared .. not the X .. but the website didnt allow me to do that so =/ ... but i hope this helps =)
