Another day, another lab! For our last practice lab before the grade 11 chemistry summative, we combined a solution of copper sulfate with iron. Using knowledge from many of our previous chemistry units, we found the limiting reagent and compared the moles of the elements to determine the valence of copper.
After we learned integration by parts in grade 11 AP calculus, we went on a tangent to apply this knowledge to trigonometric functions and substitutions. By then, we had acquired a fraction of the skills needed to integrate rational functions. With long division and partial fractions on our side, we can integrate problems of all shapes and sizes!
The grade 11 calculus class used their knowledge of derivatives to solve related rates problems. One of many real-world problems they examined was calculating the rate of change of the distance between two cars. Next, students will learn about other topics of differentiation, including local linear approximation and indeterminate forms.
