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


Concept/skill: 
Understand that by similarity, side ratios in right triangles are properties of the angles in the triangle, leading to definitions of trigonometric ratios for acute angles.

Answer: 
No. This problem does not directly teach how side ratios in right triangles lead to definitions of trigonometric ratios. Instead, it involves solving a trigonometric function.

Now, does the problem or activity shown below enable students to learn the full intent of the following concept or skill?

standard_description: Represent addition and subtraction with objects, fingers, mental images, drawings (Drawings need not show details, but should show the mathematics in the problem. (This applies wherever drawings are mentioned in the Standards.)), sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.
problem_activity: For lunch, you order a pizza and drink some milk.
The pizza is cut into 8 slices, and you eat 3 of the slices. The pizza box says that the serving size is 2 slices, and there are 570 calories per serving.
The milk is in a quart container, and you drink 1 cup of it. The milk carton says that there are 580 calories in the entire quart.
How many calories did you eat for lunch? If you are trying to stick to a limit of 2,000 calories for the day, then what percent of your daily calories did you just eat for lunch?
