P l e a s e space c h e c k space y o u r space q u e s t i o n : Q u e s t i o n space s h o u l d space b e : I f space cos A plus sin A equals square root of 2 cos A comma space t h e n space p r o v e space t h a t space cos A minus sin A equals square root of 2 sin A. S o l u t i o n : C o n s i d e r space t h e space g i v e n space e q u a t i o n : cos A plus sin A equals square root of 2 cos A rightwards double arrow sin A equals square root of 2 cos A minus cos A rightwards double arrow sin A equals open parentheses square root of 2 minus 1 close parentheses cos A rightwards double arrow fraction numerator sin A over denominator cos A end fraction equals square root of 2 minus 1 rightwards double arrow fraction numerator sin A over denominator cos A end fraction equals fraction numerator square root of 2 minus 1 over denominator square root of 2 plus 1 end fraction cross times square root of 2 plus 1 rightwards double arrow fraction numerator sin A over denominator cos A end fraction equals fraction numerator 2 minus 1 over denominator square root of 2 plus 1 end fraction rightwards double arrow fraction numerator sin A over denominator cos A end fraction equals fraction numerator 1 over denominator square root of 2 plus 1 end fraction rightwards double arrow cos A equals open parentheses square root of 2 plus 1 close parentheses sin A rightwards double arrow cos A equals square root of 2 sin A plus sin A rightwards double arrow cos A minus sin A equals square root of 2 sin A
