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

LekaFEV [45]

By applying the formula of trigonometric function the right hand side will

be equal to right hand side which is 1- $tan^{2} x$ / $sec^{2}x$ =cos2x.

Given: 1- $tan^{2} x$ / $sec^{2}x$ =cos2x.

Taking right hand side first which is cos2x.

We know that cos2x= $1-tan^{2}x/1+tan^{2}x$

Now we will solve the left hand side of the equation give which is

1- $tan^{2} x$ / $sec^{2}x$

=1- $tan^{2}x$ /1+ $tan^{2}x$

[secant square x minus tangent square x is equal to 1]

By putting both values left hand side and right hand side we will find our solution which is :

1-tan^{2}x/1+tan^{2}x=1- $tan^{2}x$ /1+ $tan^{2}x$ .

Hence proved

Scorpion4ik [409]

Answer:

slope 4/5

Step-by-step explanation:

The attachment shows the rise in green (4 grid squares), and the run in red (5 grid squares). The slope is the ratio rise/run.

The slope is rise/run = 4/5.
