Problem/activity:
Find the general solution for:
$${\mathrm{cos}\left({\pi\over2}+x\right)=\mathrm{tan}{\pi\over4}}$$


Description: 
Prove the addition and subtraction formulas for sine, cosine, and tangent and use them to solve problems.

Answer: 
Yes. An initial step when solving for x in this problem requires the use of the addition formula for cosine on the left side of the equation.

Now, assess whether the following problem or activity aligns with the provided description.

Below is a table of diameters of different denominations of United States
Coins:
{"table": [{"_attributes": {"class": ["centered", "narrow"]}, "tbody": [{"tr": [{"th": [{"_value": "Denomination"}, {"_value": "Diameter"}]}, {"td": [{"_value": "Dime"}, {"_value": "$17.9$ mm"}]}, {"td": [{"_value": "Nickel"}, {"_value": "$21.2$ mm"}]}, {"td": [{"_value": "Quarter"}, {"_value": "$24.3$ mm"}]}, {"td": [{"_value": "Half Dollar"}, {"_value": "$30.6$ mm"}]}]}]}]}
If we place nickels around a central dime, as in the picture below, there is room
for five nickels with extra space but not enough room for a sixth nickel:
[IMG]
How many dimes fit around a central dime?  What about around a
central nickel, quarter, or half dollar?  Do the dimes fit snugly or is there
extra space?
How many half dollars fit around a central dime?  What about around
a central nickel, quarter, or half dollar?  Do the half dollars fit snugly or
is there extra room?
Extending the work in (a) and (b) above, for positive numbers $r$ and $s$
how many circles of radius $s$ will fit around a central circle of radius $r$?


aligns: yes
