thanks sir......and happy diwali.......
Hi, one way is to write cosnx = (e inx + e -inx ) / 2 and integrate it normally. Now, it is very easy to integrate....
Be the first one to answer
a, b, c are in AP, ie, b = a + d, c = a + 2d x, y, z are in GP, ie. y = xr, z = xr 2 The area of triangle is ½ |a(y – z) + b(z – x) + c(x – y)| Consider a(y – z) + b(z – x) + c(x – y) = a(xr – xr 2 )...
sir please answer other problems too.......i have tried them multiple times.......atleast provide the hints
Ans: Hello Student, Please find answer to your question below sinx should be b/w 0 & 1 (with both excluded) Since base(sinx) is less than 1. So when we cancel it out, inequality sign will change...
please answer rest of the problems posted …....
SIR ATLEAST PLEASE ANSWER OTHER PROBLEMS.............
Hi Student, Hope you are doing good. We are regularly answering the questions. We will be happy to help students like you. Please send your unanswered questions again. We will revert back as soon as...
Hi Student Please note integration of this function is not possible by standard calculas methods. So this cannot be integrated. . . . . .
let u = x ; v = cosnx du = dx; ∫v = sinnx/n This is in the form of ∫uv = u∫v – ∫∫v.du ∫xcosnxdx = xsinnx.n – ∫sinnx/n dx = xsinnx/n – ( – cosnx/n)/n = xsinnx /n + cosnx / n 2
Hi, Just differentiate your answer with respect to x, if you are getting the original function (as in the question), then your answer is correct, otherwise wrong....
Hi, Find the slope of tangent by differentation. The slope will be 2x+3, Here x is the point on the curve. Let it be h. So slope will he 2h+3. Equation of tangent passing through origin will be y =...
Ans: Hello Student, Please find answer to your question below
Dear student, Put x = tan and simplify it to very simple integral and find the answer. Thanks
Hi, Convert all the terms in 2x angle and put COS2x = t. You will get the differential in the denominator. Convert the integral in t and do the partial fraction. After this step ull see that the...
Sorry, Pl. ignore, this is a wrong solution
