WebMay 9, 2024 · f( − x) = f(x) for all x in the domain of f The graph of an even function is symmetric about the y- axis. The cosine function is an even function because cos( − θ) = cosθ. For example, consider corresponding inputs π 4 and − π 4. The output of cos(π 4) is the same as the output of cos( − π 4). Thus, cos( − π 4) = cos(π 4) ≈ 0.707 See Figure 9.1.3. WebFirst, re-write the equation so that it is equal to zero: Now we can use the quadratic formula to solve for x. In this case, the coefficients a, b, and c are a=1, b=2, and c=-3: simplify. This gives two potential answers: and. Sine must be between -1 and 1, so there are no values of x that would give a sine of -3. The only solution that works is .
