Question

Find all values of x for which the line that is tangent to y = 3x - tan x is parallel to the line
y - x = 2 ?

Answer 1

also solve in steps sec(xy) = y find dy\dx?

Answer 2

find dy/dx of y=3x-tanx

Answer 3

the gradient of the tangent is the same as the gradient of the parallel line

Answer 4

you write the equation of the parallel line in y=mx+c
\[y=x+2\]

Answer 5

this means gradient of tangent is
\[M_t=1\]

Answer 6

the gradient of the tangent is also the gradeint of 3x-tanx

Answer 7

the question seems pointless let @campbell_st

Answer 8

ok i see thx any way
