Approved Tutor Answer8 Years agointegration of sinx+cosx=integration of sinx + integration of cosx
integration of sinx =-cosx
applying limits feom 0 to pi/2 i.e,-cospi/2-(-cos0)=0+1=1.............A
integration of cosx=sinx applying limits from pi/2 to 0 i.e.,sinpi/2-sin0=1............B
Adding a and b i.e,1+1=2

Approved Tutor Answer8 Years agoIntegral of sin x = - cos xInyegral of cos x = sin xHence integral of question will be = Sinx - cos xBut if apply the limitThen answer == Sin (pi/2) - cos(pi/2) -[sin 0 - Cos 0]= 1- 0 - 0 + 1=2

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
