If the value of `lim_(x->-oo)[x^5tan(1/[pix^2])+3x^2+7]/[|x|^3+7|x|+8]` is equal to `-K/ pi`,then `K=`

(lim)_(x->oo)((2tan^(-1)x)/pi)^x

The value of lim_(xrarr-oo)(x^(2)tan((1)/(x)))/(sqrt(4x^(2)-x+1)) is equal to

The value of lim_(xrarr-oo)(x^(2)tan((2)/(x)))/(sqrt(16x^(2)-x+1)) is equal to

the value of lim_(x rarr oo)((x^(2)+5x+3)/(x^(2)+x+2))^(x)

lim_(x rarr-oo)(x^(2)tan((1)/(pi x^(2)))+3|x^(2)|+7)/(|x^(3)|+7|x|+8) is equal to: a*-(1)/(pi) b.0 c.oo d.Does not exist

The value of lim_(xrarr1) (2-x)^(tan.(pix)/(2)) is equal to

The value of lim_(x rarr oo)(x+2)tan^(-1)(x+2)-(x tan^(-1)x) is
