lim_(x to oo)(sin^(4)x-sin^(2)x+1)/(cos^(4)x-cos^(2)x+1) is equal to

lim_(xtooo) (sin^(4)x-sin^(2)x+1)/(cos^(4)x-cos^(2)x+1) is equal to

(lim)_(x rarr)(sin^(4)x-sin^(2)x+1)/(cos^(4)x-cos^(2)x+1) is equal to (a) 0( b) 1 (c) (1)/(3)(d)(1)/(2)

the value of lim_(x rarr pi)(1)/(x-pi)(((4cos^(2)x)/(2+cos x))^((1)/(2))-2) is

If 4cos^(2)x-2(1+sqrt(3))cosx+sqrt(3)=0 the solution set in [0,pi] is

If "sin" x + "sin"^(2) x = 1 show that: cos^(4)x + cos^(2)x = 1 (ii) If "sin" x + cos x =sqrt(2) cos x show that: sqrt2 sin x = cos x - sin x

Let RR be the set of all real numbers and f(x) = sin^(10)x(cos^(8) x+cos^(4)x + cos^(2)x+1) for x in RR . Let S = {lambda in RR | there exists a point c in (0, 2pi) with f'(c) = lambda f(c) }.
