" (ii) If "2x=sec A" and "(2)/(x)=tan A," then the value of "2(x^(2)-(1)/(x^(2)))" is "(a)(1)/(2)(b)(1)/(4)(c)(1)/(8)(d)

If 4x = sec theta and (4)/(x) = tan theta then 8 (x^(2) - (1)/(x^(2))) is

The derivative of tan^(-1)((sqrt(1+x^(2))-1)/(x)) with respect to tan^(-1)((2x sqrt(1-x^(2)))/(1-2x^(2))) at x=0 is (1)/(8)(b)(1)/(4)(c)(1)/(2)(d)1

If 4x = sec theta and 4/x = tan theta , then 8(x^2 -1/x^2) is

If sec theta+tan theta=x, then sec theta=(a)(x^(2)+1)/(x) (b) (x^(2)+1)/(2x)(c)(x^(2)-1)/(2x) (d) (x^(2)-1)/(x)

If sec theta+tan theta=x, then tan theta=(x^(2)+1)/(x) (b) (x^(2)-1)/(x)( c) (x^(2)+1)/(2x) (d) (x^(2)-1)/(2x)

If sec theta=x+(1)/(4x), then sec theta+tan theta=x,(1)/(x) (b) 2x,(1)/(2x)(c)-2x,(1)/(2x)(d)-(1)/(x),x

The value of lim_(x->1)(1-sqrt(x))/((cos^(-1)x)^2) is (a)4 (b) 1/2 (c) 2 (d) 1/4

If sec x+sec^(2)x=1 then the value of tan^(8)x-tan^(4)x-2tan^(2)x+1 will be equal to 0(b)1(c)2(d)3

The value of (cot((x)/(2))-tan(x)/(2))^(2)(1-2tan x cot2x) is 1 (b) 2(c)3(d)4
