                                        Ans:$y = sin^{-1}(x^{2}-\frac{a}{x^{2}}+1)$$(x^{2}-\frac{a}{x^{2}}+1)=siny$$x^{4}+(1-siny)x^{2}-a=0$This is simple Quadratic in x2,$\Delta \geq 0$$(1-siny)^{2}\geq 4.(-a)$$sin^{2}y-2siny+1+4a\geq 0$$\Delta <0$$4<4(4a+1)$$a>0$Thanks & RegardsJitender SinghIIT DelhiaskIITians Faculty

find the sum of a infinite geometric series whose first term is the limit of the function f(x)=(tanx-sinx)/(sinx)^3 as x tends to 0 and whose common ratio is the liit of the function...

for f(x) divide numerator denominaor by x^3.... then use expansion series... I couldn’t understand what g(x) is so pls rewrite that

question is in image

Step 1: C3 = C3 – C2*x, Step 2: R3 = R3 + R2, Step 3: C1 = C1 – 50*C2, Step 4: Expand the determinant You will get Dx = 2x(-50) + 500, Sum(Dx) = -500
