यदि ` y= (5x) /(3sqrt 1-x^(2) )+ sin ^(2) (2x+ 3),` तब ` (dy)/(dx) ` का मान ज्ञात कीजिए |

Answer» यदि ` y= (5x) /(3sqrt 1-x^(2) )+ sin ^(2) (2x+ 3),`
` therefore (dy)/(dx) =(d)/(dx) {5x(1-x^(2) )^(-1//3) }+ (d)/(dx) {sin ^(@) (2x+ 3)} `
` = {5x*(-(1)/(3) ) (1-x^(2) )^(-4//3) *(-2x ) + ( 1-x^(2) ) ^(-1//3)*5} `
` " "+ {2sin (2x+3) cos (2x+ 3)*2}`
` =(10x^(2))/( 3(1-x^(2) )^(4//3) )+ (5)/((1-x^(2) )^(1//3))+2sin (4x+ 6) `
` =((10x^(2) + 15(1-x^(2)))/(3(1-x^(2))^(4//3) )+2 sin (4x+6) `
` = (15-5x^(2) ) /(3( 1-x^(2) ) ^(4//3))+2sin (4x+6 ) `
