x-y=2

Differentiate y=x^sinx+(sinx)^cosx

here  there is open interval 1,2 (1,2) that means we shouldn't include 1&2 right but u hv taken as x=1 & x=2 why..?

Find the equation of line through the intersection of line 3x 4y=7 and x-y 2=0 and whose slope is 5

draw a triangle ABC with bc 7cm angle B45 angle A105 then construt triangle whose sides are 4/3 times the corresponding sides of triangle ABC

 chapter 8

this is a simple step.
