In ‘A Streetcar Named Desire,’ creating the illusion of being, ‘attractive…prim and proper,’ is all Blanche can do to satisfy her yearning to maintain the ‘beauty’ and gentility of her ‘fading’ youth; pre...

Let A=7x and B=3x( From the formulae we know that sinxcosx= 1/2(sin(A+B)+sin(A-B))So if we replace A=7x and B=3x in this equation: 1/2(sin(7x+3x)+sin(7x-3x))= = 1/2 (sin(10x)+sin(4x))Now we just integrate...

Let u=6x-3 , then y=u^-0.5hence, du/dx=6 and dy/du= -0.5u^-3/2then, as dy/dx =dy/du * du/dx dy/dx=(-0.5u^-3/2 )*6= -3(6x-3)^-3/2substitute x=2 to give the required value required value : -1/9

There isn't one way to write a great introduction, so be flexible and allow your response to the specific question you've been asked inform how you go about introducing your argument. Whatever your approa...

A wave of depolarisation is sent toward the neuromuscular junction, this causes voltage gates Ca2+ channels in the presynaptic membrane to open allowing the Ca2+ ions to enter following their concentratio...
