If _________

_/ 3x +1

f (x) = (for x ≥ 0)

Find f' (x) by using formal definition of derivatives

Differentiate it with respect to x

f (x) = cosx. cosec x / -1 +x . cot x

Find the derivative of

f (x) = sin 3x^2 / (3x+1)^2

thanks in advance for ur help

By using squeezing theorem we can prove that

limxsin (1/x) = 0

x -->0

Why couldn’t we have the same result by writing

limxsin (1/x)= limx.limsin (1/x)=0.limsin (1/x)=0 ?

x -->0 x-->0 x -->0

Thanks for ur help

Find the value of constant k so that

f (x) = { sin 3x / x x =0

k x=0

Will be continuous at x=0.

Thanks for ur help in advance

find the value of x which function is not continuous

a) f (x) = 3x + 1/ x^2 + 7x -2

b) f (x) = 7/x + 3x / x+6

Thanks for ur great help in advance

x, y, w and z are Boolean variables. Make the truth table for the expression given below.

z = NOT( x XOR y ) AND w

Thanks for ur great help in advance

Solve the inequality

-6 < 4 - 2x / 3 < 1

its really appreciated

Determine whether the equation represents a circle, if the equation represents a circle, find the center and radius.

x2 + 2x + y2 - 4y = 5

its really appreciated

let

f(x) = x /x+3 and g (x ) = x^2

find whether (f o g) (x) and (g o f ) (x) are equal or not ?

its really very very very urgent

Whether the given lines are parallel, perpendicular or none of these.

( y-1)/2= x-3 & 8-2y = x+7

its realy very urgent
