One side of a right triangle is known to be 9 cm long and the opposite angle is measured as 30°, with a possible error of ±1°. (a) use differentials to estimate the error in computing the length of the hypotenuse. (round your answer to two decimal places.)

Hypotenuse, L= 9 cosec x dL = 9 Cosec x *( cot x) dx dx( error in angle)=1 deg = Pi/180 radians dL,(error in Length of Hypotenuse at x= 30 deg)= 9* cosec 30* cot 30* PI/180 = 9*2*4*Pi/180 = 2/5 * Pi/180 It indicates 1% error in angle measurement result in 40% error in Length measurement Source(s): My children's doubts in mathematics and involvement to help them using my experience of education Now they are grown up let me see happiness in other child
