# C3 Review Exercise 2 Question 8b watch

1. http://pmt.physicsandmathstutor.com/...ercise%202.pdf

For the graph drawn, there are six intersection points. But in the final answer, it shows that there are only 4 solutions.

I understand how to get those 4 solutions, but what about the x = 1.57 and x = -1.57 radians? Shouldn't this be included in the final answer?

they have not put all 6 answers together at the end, but they do want all 6.

In the Edexcel textbook for C3, they also only give those 4 solutions. The textbook only shows answers. So that is most likely why solution bank got it wrong too.
