Best ResponseYou've already chosen the best response.0\(\sqrt{(1sin{\theta})(1+sin{\theta})}\) \(\sqrt{(1sin^2{\theta })}\) But \(cos^2{\theta} + sin^2{\theta} = 1\), then \(\sqrt{cos^2{\theta}}\) \(\pm cos{\theta}\)

Best ResponseYou've already chosen the best response.0\(cos(x\pi/2) = sin(x)\) and \(sin(x  \pi/2)=cos(x)\)

Best ResponseYou've already chosen the best response.0So, which one you think is the right answer?

Best ResponseYou've already chosen the best response.0No. From the graph we see that f(x) at x = 0 is 0, that means f(x) is some function of sin(x), since sin(x) at x = 0 is 0

Best ResponseYou've already chosen the best response.0In that case, the first one we have \(sin(x\pi/2) = cos(x)\), so that can't be the right answer

Best ResponseYou've already chosen the best response.0If we check the last option, we have \(cos(x\pi/2) = sin(x)\), but from the graph we also get the information that f(x) at x = pi/2 is equal to 4. But sin(x) at x = pi/2 is equal to 1. That tells us that we need a 4 multiplying this sin(x). So... The last option is the correct answer
