Csc²x - 1
1/sin²x - 1
1/sin²x - sin²x / sin²x
(1 - sin²x) / sin²x
Recall that sin²x + cos²x = 1
So cos²x = 1 - sin²x
So we can replace numerator to cos²x
cos²x / sin²x
= cot²x
Final answer: cot²x
<span>M1=[<span>(4a+0)/2 <span>,(4b+0)/2] = (2a, 2b)
</span></span></span>M2=[(4c+4d)/2 ,(4b+0)/2] = [2(c+d) , 2b]
answer
coordinate points (x,y) :
(2a, 2b) , [2(c+d) , 2b]
Answer:
7x+1/4
Step-by-step explanation:
5x+3/4+2x+-1/2
Combine Like Terms:
5x+3/4+2x+-1/2
(5x+2x)+(3/4+-1/2)
7x+1/4
Hope this helps
In this equation, you have to treat the number in the bracket first on the basis of BODMAS
15 - [-3]- 4
Note that when two minuses come together the product is a plus sign.
15 +3 - 4
You have to add before you subract
18 - 4 =14
Therefore, 15- [-3] - 4 = 14.
Answer:
2^3·2^2 = 2^3+2 = 2^5
Step-by-step explanation:
Diego was trying to write 2^3 · 2^2
He wrote 2^3·2^2 = 2^3*2 = 2^6
But this is wrong because when bases are same exponents are added.
This is the law of exponents.
The correct form would be
2^3·2^2 = 2^3+2 = 2^5
For understanding it better we can write it like this
2^3·2^2 =
There are 3 two and 2 twos .When totaled there are 5 two not 6 twos.
