The equation of the normal to the curve y=sinX at the point (pie,0) |
Answer» Answer :y = x - π SOLUTION :Here , The given CURVE is y = sinx ----(1) Now , Differentiating eq-(1) both sides with respect to x , we get ; => dy/dx = d(sinx)/dx => dy/dx = cosx => Slope of tangent = cosx At (π , 0) => Slope of tangent = cosπ => Slope of tangent = -1 Also , We KNOW that , the product of mutually perpendicular lines = -1 Thus , => Slope of tangent • Slope of normal = -1 => -1 • Slope of normal = -1 => Slope of normal = -1/-1 => Slope of normal = 1 Also , We know that , the equation of a straight line PASSING through point (x1 , y1) with slope m is given by ; (y - y1) = m(x - x1) Thus , The equation of the normal line at point (π , 0) and having the slope = 1 will be given as ; => (y - 0) = 1•(x - π) => y = x - π HENCE ,Required equation of normal is y = x - π |

Find the value of x and y if ( 5x - 3y, 3x-y ) = ( 16,12 ) |
|
Answer» Answer: Step-by-step explanation: 5x - 3y = 16 -------> eq 1. 3x - y = 12 multiply - 3 on both sides, - 9x + 3y = - 36 -------> eq 2. Add eq 1 and eq 2, 5x - 3y = 16 -9x +3y = -36 __________ -4x + 0 = -20 -4x = -20 x = - 20 / - 4 x = 5 SUBS in eq 1, 5x - 3y = 16 5 ( 5 ) - 3y = 16 25 - 3y = 16 - 3y = 16 - 25 - 3y = - 9 y = - 9 / - 3 y = 3 |
