21−=2(2−)=2cos(−1)+2 sin(−1)
−1+2=−1(2)=−1(cos2+sin2)=cos2+ sin2
Is the above the correct way to write 21− and −1+2 in the form +? I wasn't sure if I could change Euler's formula to =cos()+sin(), where is a constant.

No. It is not true that =cos()+sin(). Notice that
1=1≠cos()+sin(),
for example consider this at =0.
As a hint for figuring this out, notice that
+=ln(+)
then recall your rules for logarithms to get this to the form (+)ln().

So, the inequality is
Step-by-step explanation:
Since, the shape of ocean front is rectangular
Let's assume length of rectangle is x feet
width of rectangle us y feet
we are given
An ocean front lot has a perimeter of 250 feet
so, we get
now, we can solve for y
now, we can find area
now, we can plug back y
an area of at least 2500 square feet
so, we get
