Prove the following identity sin x(sec x+cscx)= tan x +1

Alexxandr [17]

Answer:

Step-by-step explanation:

________________________________________________________

FACTS TO KNOW BEFORE SOLVING :-

$\sin x = \frac{1}{cosec \: x} \: \: or \: \: cosex \: x = \frac{1}{\sin x}$

$\cos x = \frac{1}{\sec x} \: \:or \: \: \sec x = \frac{1}{\cos x}$

$\tan x = \frac{\sin x}{\cos x}$

________________________________________________________

In the question ,

L.H.S. = $\sin x (\sec x + cosec \: x)$

R.H.S. = $\tan x + 1$

Lets solve L.H.S. first.

$\sin x (\sec x + cosec \: x)$

$=> \sin x( \frac{1}{\cos x} + \frac{1}{\sin x} )$

$=> \frac{\sin x}{\cos x} + \frac{\sin x}{\sin x}$

$=> \tan x + 1$

∴ L.H.S. = R.H.S. (Proved)

PLEASE HELP IM SO CONFUSED

Answer:

Your answer is 5 weeks!!

Step-by-step explanation:

How I got my answer; First I checked if 2 weeks would work by doing 2( the umber of weeks) *3( the number of inches it grows per week) which is 6, I then added 6 to 3 inches (which is the original height of the plant) and I got 9.

I did the same process with the 2nd plant;

2(the number of weeks) *2( the number of inches the plant grows per week) which is 4. I then added 4 and 8( the original height) and I got 12.

(THE EXPLANATION FOR HOW I GOT 5 WEEKS STARTS HERE)

So I continued to do this process with 2,3,4 and 5, and finally I got my answer at 5weeks.

5(the number of weeks) * 3(the rate the plant grows per week) which is 15inches. I then added 15 to the original height which is 3inches, 15 +3 is 18 inches so that is my answer for how tall the 1st plant would get in 5 weeks .

Now the 2nd plant;

5(the number of weeks) * 2(the rate the plant grows per week) which is 10inches. Now I'm going to add the original height (8) with the rate the 2nd plant would grow after 5 weeks (10), 10+8 is 18 so the plant would grow 18inches after 5 weeks which is the same height as the first plant.

Hope this makes sense :)
