WebJun 27, 2024 · One way I have used to view the symmetry between the equations sin(x)=cos(90-x) is by visualizing two triangles: two triangles with complementary angles. In the above image, you can find that the cosine of theta is x/hyp, while the sin of 90-theta is x/hyp. Seeing it graphically helped he visualize how these two functions were related.
