If sinA=-513,蟺<A<3蟺2, and cosB=2425,3蟺2<B<2蟺, what is sinA+B?
Let y=y(x) be the solution of the differential equation, xy'-y=x2(xcosx+sinx),x>0.Ify(蟺)=蟺, then y''蟺2+y蟺2 is equal to:
If -蟺<argz<-蟺2, then argz炉-arg-z炉 is equal to
What is the sum, of 'n' terms in the series:
logm+logm2n+logm3n2+logm4n3+......
How do you find the exact values of sinu2,cosu2,tanu2 using the half angle formulas given cotu=3,蟺<u<3蟺2?
