Verify that -tan2x = (2tanx) / (sec^2x - 2)
sashaice [31]

Answer:

Below.

Step-by-step explanation:

- tan 2x =   -2tanx / (1 - tan^2x)

Using the identity  tan^2x = sec^2x - 1 and substituting for tan^2x:

- tan 2x = -2 tanx / (1 - (sec^2x - 1))

=   2 tanx / ( - 1(sec^2x + 2))

= 2 tan x / (sec^2 x - 2)

A line includes the points (6,9) and (14, 17). What is its equation in slope-intercept form?
Firlakuza [10]

Answer:

y = x + 3

Step-by-step explanation:

Given: (6,9)  (14, 17)

m=\frac{y_{2}-y_{1}  }{x_{2}-x_{1}  } = \frac{17-9}{14-6}=\frac{8}{8}=1

slope, m = 1

Equation of line ⇒ y=mx+b

y = 9 , x = 6 , m = 1, b = ?

9 = 1*6 + b

9 = 6 + b

b = 9 - 6 = 3

Therefore, the equation of line will be:

y = 1x + 3

y = x + 3
