Tan x /(1 +sec x) + (1+sec x) /tan x
Tan x=sin x / cos x
1+ sec x=1 +1/cos x=(cos x+1)/cos x
Therefore:
tan x /(1 +sec x) =(sin x/cos x)/(cos x+1)/cos x=
=(sin x * cos x) / [cos x* (cos x+1)]=sin x /(Cos x+1)
(1+sec x) /tan x=[(cos x+1)/cos x] / (sin x/cos x)=
=[cos x(cos x+1)]/(sin x *cos x)=(cos x+1)/sin x
tan x /(1 +sec x) + (1+sec x) /tan x=
=sin x /(Cos x+1) + (cos x+1)/sin x=
=(sin²x+cos²x+2 cos x+1) / [sin x(cos x+1)]=
Remember: sin²x+cos²x=1⇒ sin²x=1-cos²x
=(1-cos²x+cos²x+2 cos x+1) / [sin x(cos x+1)]=
=2 cos x+2 / [sin x(cos x+1)]=
=2(cos x+1) / [sin x(cos x+1)]=
=2 /sin x
Answer : tan x /(1 +sec x) + (1+sec x) /tan x= 2/sin x
I think it might be 2x^2 + 2x + 2xy
Rs is 66, Sixty six, according to diagram
Answer:
11x+4+5=180 ok first we have to put all the naked numbers on one side and the x's number on one side, and by doing that a easier way to do that is you switch the spots but their symbols - and + change so if its negative - its going to turn into a + positive and + to a -
11x = 180 - 5 - 4
11x = 171 and since theres mutliplication 11 times x which is 11x, were going to divide
x = 171/11 and the out come is with decimals (15.54545...etc)
x=11 is incorrect
~batmans wife dun dun dun....
Using proportions, it is found that she spent 25.76 hours at Yoga.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount.
Researching the problem on the internet, it is found that the circle graph shows that she spent 28% of her time of 92 hours on yoga, hence:
h = 0.28 x 92 = 25.76.
Hence, she spent 25.76 hours at Yoga.
