SUMMARY

The discussion focuses on maximizing the area of a triangle with adjacent sides measuring 4 cm and 6 cm. The key to solving this problem lies in using the formula for the area of a triangle, A = 0.5 * a * b * sin(θ), where 'a' and 'b' are the lengths of the sides and 'θ' is the angle between them. To find the angle that maximizes the area, one must recognize that the maximum occurs when sin(θ) is at its peak value of 1, which corresponds to an angle of 90 degrees. Thus, the maximum area is achieved when the angle between the sides is 90 degrees.

PREREQUISITES
  • Understanding of basic trigonometry, specifically sine functions.
  • Familiarity with the area formula for triangles.
  • Knowledge of how to differentiate functions to find maxima.
  • Ability to apply the sine law in triangle problems.

Homework Statement


A triangle has adjacent sides 4 cm and 6 cm. Find the angle contained by the sides which maximizes the area.


Homework Equations





The Attempt at a Solution


I'm not going to lie. I have no idea how to start this. I tried using sine law to create a helper equation but that gave me Four unknowns.
