Hello Mohan The question is not clear, could you post what needs to be proved in this question.-------------------
Here if U are using log expansion then write for cos function too. lim x-> 0 becomes: => (x(1-x^2/2) – (x – x^2/2))/x^2 => (1-x^2/2) – 1 + x/2)/x => (-x^2/2) + x/2)/x => (-x/2 + 0.5)/1 => 0.5 would...
Differentiate it first and then equate it to zero. 2cos2x – 1 = 0 cos2x = ½ 2x = pi/3 x = pi/6 or 2cos^2x – 1 = ½ cos^2x = ¾ cosx = root3/2 and also, cosx = -root3/2 x = pi/6 and x = -pi/6 check at...
put x = 2 in Lim x->2 (2/(x+2) + 1/x2-2x+4 - 24/(x3+8) =>2/4 + ¼ – 24/16 => 0.5 + 0.25 – 1.5 = > -.75 or -3/4
y = (ax+b)/(cx+d) multipy and divide by c y = (acx+bc)/c(cx+d) add and subtract ad y = (acx+ad+bc-ad)/c(cx+d) take a common from the first two terms y = a(cx+d) +bc-ad/c(cx+d) y= [a(cx+d)/c(cx+d)] +...

If the pair of state lines joining the origin to the point of intersection of the ellipse x²∕𝐲²+y²⁄𝐛²=1 and the line 𝑙𝑥+𝑚𝑦+𝑛=0 are parpandecular to each other then show that...
the period of tan6x is pi/6 and the period of cos4x is 2pi/4 that is pi/2 and then we take L.C.M of (pi/6,pi/2) that is pi/2.
I think the answer is 2pi because |sinx| period is pi and also |cosx| period is pi when we add we get 2pi
This question should have been posted in algebra section . Anyway here is solution. It was easy, wonder why you cant do it
Here is my attempt to solution, let me know if it is correct........................................................................
DEAR SURI, ORDINARY DIFFERENTIAL EQUATIONS IS USED IN DESIGNING IN AIRCRAFTS AND IT IS VERY IMPORTANT SUBJECT FOR GATE.
First you need to draw graph for max (sinx, cosx ) as follows Draw combined graphs of both sinx and cos x so that at some places graph of sin x will be higher and at other cosx will higher. Take only ...
DEAR SREEKANTH, THE DIMENSION OF A SPAN SET IS DEFINED AS THE NUMBER OF ELEMENTS PRESENT IN THE THAT SET.
DEAR RAJ, VECTOR SUBSPACE OF A VECTOR SPACE IS DEFINED AS IT WILL SATISFIES THE THREE PROPERTIES THOSE ARE ADDITION OF NULL VECTOR AND ADDITION OF VECTORS AND SCALAR MULTIPLICATION.
DEAR RAJ, SPAN OF A SET IS DEFINED AS THE GENERAL FORM OF A SET OF POINTS WHICH IS IN THE FIELD OF REAL NUMBERS.
I hope you want to ask why domain of arcsin cannot be greater than 1. by definition of inverse function the the domain of arcsin = range of sin function. Now range of sin function is [-1, 1 ] Hence...
DEAR NAG, The linear span (also called the linear hull or just span) of a set of vectors in a vector space is the intersection of all subspaces containing that set. It is very useful thing.
DEAR NAG, A MATRIX IS IN REDUCED ROW ECHLON FORM IF IT SATISFIES THE FLLOWING CONDITIONS :IT IS IN ROW ECHLON FORM.
DEAR NAG, AN O.D.E IS AN EQUATION THAT INVOLVES SOME ORDINARY DERIVATIVES OF A FUNCTION.OFTEN OUR GOAL IS TO SOLVE ODE ,DETERMINE WHAT FUNCTION OR FUNCTIONS SATISFIES THAT EQUATION.
@ karan frst of all complete your ncert , then do the exercises as well as miscellenous given in the ncert , then switch up to exempler and solve each and every question their . after that choose...
Hii The question iss not clear . Repost the question and we will get back at you.
Since this of form 0/0 use L Hospital rule. Differentiating numerator and denominator it becomes (m sin mx)/ (n sin nx) This is again of form 0/0 , hence differentiating again (m 2 cos mx)/ (n 2 cos...
