Hi
\(\frac{cos^2(x)-sin^2(x)}{cos^2(x)+sin(x)cos(x)}=1-tan(x)\\~\\ LHS=\frac{cos^2(x)-sin^2(x)}{cos^2(x)+sin(x)cos(x)}\\ LHS=\frac{(cos(x)-sin(x))(cos(x)+sin(x))}{cos(x)(cos(x)+sin(x))}\\ LHS=\frac{cos(x)-sin(x)}{cos(x)}\\ LHS=1-tan(x)\\ LHS=RHS\qquad \qquad QED\)
Here are the 2 graphs that you talke about. You can see they are not the same.
You have to first find a common denominator. List out the multiples of 3 and 9.
3: 3,6,9,12,15,18,21,24,27,30...
9:9,18,27,...
9 is the simplest.
Multiply 2/3 by 3 and you will get 6/9.
2 2/9 - 6/9= 1 5/9
Please correct any mistakes I may have made.
mathguardian: You got it backwards !!
You cannot find the surface are because it is not 3 dimensional but maybe I could find the area.
I think I need more info ... like maybe that it is a trapezium for example ???
I still have at least 22 days left. : (
good luck and have a nice summer
I still have a whole week of exams
Why lol?
im going to
my sis says that homeschool moms dont believe in summer breaks lol
yes!! have a nice summer i finish today the school's subjects and in 11days 07/06/2017-14/06/2017 i give my most important examinations in my life until now for university in maths/chemistry/physics have a nice summer and goob results!!!
NOT ME :) im homeschooled so i have to finish
2 2/9 - 2/3
4/9-2/3
4/9-6/9=-2/9
Because life's life is life.
I would go more along the lines of:
1.25 125
______ = _____
0.75 ?
125 * 0.75 = 93.75
93.75 / 1.25 = 75
I'm not sure about my math, but is it $75?
Yes it would be 24 :)
28/13 = 2.1538461538461538
Would it be 24?
Thank you. And I have to thank my math teacher for that too! : )
The multiples of 6 are 6,12,18,24,30, 36,......
The multiples of 8 are 8,16,24,32,40,48, ....
Which is the lowest common one ??
Ignore this message...
I'm sorry dude I couldnt read
yours, it got cut off
