Here is an example project that could be included:

Project: Exploring the Properties of Triangles

1. Problem Statement: Investigate the relationship between the sides and angles of a triangle using the Law of Sines and the Law of Cosines. Given a triangle with sides $a = 5$, $b = 7$, and angle $C = 60^\circ$, find the length of side $c$ and the measures of angles $A$ and $B$.

2. Solution with Mathos AI:

• Law of Cosines: Use the Law of Cosines to find the length of side $c$:

$$c^2 = a^2 + b^2 - 2ab \cos(C)$$

• Substitute the given values: $c^2 = 5^2 + 7^2 - 2(5)(7) \cos(60^\circ)$
• Since $\cos(60^\circ) = 0.5$, we have $c^2 = 25 + 49 - 35 = 39$.
• Therefore, $c = \sqrt{39} \approx 6.25$.
• Law of Sines: Use the Law of Sines to find angle $A$:

$$\frac{\sin(A)}{a} = \frac{\sin(C)}{c}$$

• Substitute the values: $\frac{\sin(A)}{5} = \frac{\sin(60^\circ)}{\sqrt{39}}$
• $\sin(A) = \frac{5 \sin(60^\circ)}{\sqrt{39}} = \frac{5 (\sqrt{3}/2)}{\sqrt{39}} \approx 0.6247$
• $A = \arcsin(0.6247) \approx 38.66^\circ$.
• Angle Sum: Find angle $B$ using the fact that the sum of the angles in a triangle is $180^\circ$:
• $B = 180^\circ - A - C = 180^\circ - 38.66^\circ - 60^\circ \approx 81.34^\circ$.

3. Explanation: We first used the Law of Cosines, $c^2 = a^2 + b^2 - 2ab \cos(C)$, to find the unknown side $c$. Given sides $a$, $b$ and angle $C$, we plugged these values into the Law of Cosines formula. After, we calculated the square root to find the length of side $c$. Next, we applied the Law of Sines to calculate the measure of angle $A$. Finally, to find the measure of angle $B$, we subtracted the calculated angle $A$ and the provided angle $C$ from $180^\circ$ as the sum of all angles in a triangle equals $180^\circ$.

4. Portfolio Entry: You have a project showing your ability to apply trigonometric principles to find missing sides and angles.

Here is another example of a project for a Math Portfolio:

Project: Understanding Exponential Growth

1. Problem Statement: A population of bacteria doubles every hour. If you start with 100 bacteria, how many bacteria will there be after 5 hours? Find a formula to describe the exponential growth.

2. Solution with Mathos AI:

• Let $P(t)$ be the population of bacteria at time $t$ (in hours).
• The initial population is $P(0) = 100$.
• Since the population doubles every hour, the growth factor is 2.
• The formula for exponential growth is $P(t) = P(0) \cdot (growth \ factor)^t$.

$$P(t) = 100 \cdot 2^t$$

• After 5 hours, the population will be $P(5) = 100 \cdot 2^5 = 100 \cdot 32 = 3200$.

3. Explanation: Exponential growth is where the quantity increases by a constant factor for each unit of time. The formula used to describe the growth is $P(t) = P(0) \cdot (growth \ factor)^t$ where $P(t)$ is the population after $t$ hours, $P(0)$ is the initial population and the $growth \ factor$ is how much the population multiplies by after each unit of time. Since the population doubles every hour, the $growth \ factor$ is 2. To find the population after 5 hours, we use $P(5) = 100 \cdot 2^5$. The $2^5$ can be expanded to $2*2*2*2*2$ which is equal to 32. Multiply that by the initial population of 100 and we will have 3200.

4. Portfolio Entry: You have a project showing your ability to apply the exponential growth equation.
