Question

1.
Find the tangent line to the curve y = √x at x = 4

​

Answer 1

welcome to the concept of applications of derivatives

slope of tangent = dy /dx at X = 4

= 1/2√x = 1/4

put X = 4 in curve equation

then y = 2

then

point of tangent (4,2)

equation of tangent by two point form is

X-4y +4 = 0
