Answer» sintsintsintsint - costcostcostcost aa - bb = (a+b)(a-b) using this we can write like following way (sintsint+costcost)(sintsint-costcost) now sintsint + costcost = 1 and costcost = 1 - sintsint = (1)(sintsint - (1 - sintsint)) = sintsint - 1 + sintsint = 2sintsint - 1 If you find this answer helpful then like it.

Answer»

sint*sint*sint*sint - cost*cost*cost*cost a*a - b*b = (a+b)(a-b) using this we can write like following way (sint*sint+cost*cost)(sint*sint-cost*cost) now sint*sint + cost*cost = 1 and cost*cost = 1 - sint*sint

= (1)*(sint*sint - (1 - sint*sint)) = sint*sint - 1 + sint*sint = 2sint*sint - 1
