Sinus Ungleichungen & Integralabschätzung beweisen | Höma2 ET&IT, HA7 A3, RWTH Aachen 2025

Homework 7 Task 3 from the Advanced Mathematics 2 ET&IT module at RWTH Aachen University (2025). In this task, we prove inequalities for the sine function and an integral estimation using the mean value theorem of differential calculus and the concavity of the sine function in the range [0, π/2].
