Answer: y=1x-1
Step-by-step explanation:
This is known as Einstein's proof, not because he was the first to come up with it, but because he came up with it as a 15 year old boy.
Here the problem is justification step 2. The written equation
BC ÷ DC = BC ÷ AC
is incorrect, and wouldn't get us our statement 2, which is correct.
For similar triangles we have to carefully pair the corresponding parts to get our ratios right:
ABC ~ BDC means AB:BD = BC:DC = AC:BC so BC/DC=AC/BC.
Justification 2 has the final division upside down.
I believe #1 is a prism and #2 is a cylinder. <span />
Answer: 1
Step-by-step explanation: the cosine function oscillates between the values -1 to 1
The amplitude of this particular function is understood to be 1
