Limit   
STatiana [176]

Rationalize the numerator:

\dfrac{\sqrt{x+4}-2}x\cdot\dfrac{\sqrt{x+4}+2}{\sqrt{x+4}+2}=\dfrac{(\sqrt{x+4})^2-2^2}{x(\sqrt{x+4}+2)}=\dfrac x{x(\sqrt{x+4}+2)}=\dfrac1{\sqrt{x+4}+2}

This is continuous at x=0, so we can evaluate the limit directly by substitution:

\displaystyle\lim_{x\to0}\frac{\sqrt{x+4}-2}x=\lim_{x\to0}\frac1{\sqrt{x+4}+2}=\frac1{\sqrt4+2}=\frac14

More trig help pls explain how you do it thank you!!!
kkurt [141]

Answer:

Step-by-step explanation:

sec x( cotx + cos x )= csc x+ 1

1/cos x( cosx/ sinx +cosx) = csc x+ 1

1/cosx ( cosx +  sinxcosx/sinx) = csc x+ 1

1/cosx( cosx) ( 1+sinx/sinx) = csc x+ 1

1(1/sinx+1) = csc x+ 1

cscx +1= = csc x+ 1
