Web19 nov. 2024 · To solve this, we first need to substitute something in order to get rid of the cos (2b). We can use the following formula: cos (2b) = 2cos 2 (b) - 1. Substituting that in gives us: 4 (2cos 2 (b) - 1) - 4cos (b) = 3. Distributing the 4 in front of the parenthesis gives us: 8cos 2 (b) - 4 - 4cos (b) = 3. If we move everything to the left-hand ...
