Finding all Trigonometric Solutions of an Equation within a Given Interval Aha, wait a moment! Following @Arturo's comment, I got $\sin x = -1/2$, which is either $7\pi/6$ or $11\pi/6$, right? |

Finding all Trigonometric Solutions of an Equation within a Given Interval I see that theres one more solution just beyond $\pi$ when I graphed the 2 functions, but I still can't reason out what it is. I tried following @Arturo's previous comment, but to no avail. |

Finding all Trigonometric Solutions of an Equation within a Given Interval Is it not just $0$ and $\pi$? |

Finding all Trigonometric Solutions of an Equation within a Given Interval I eventually simplified to the point that I got $\sin x = 0$, thus making the solutions $0$ and $\pi$. Is this correct? |

Finding all Trigonometric Solutions of an Equation within a Given Interval I'm sorry, @Srivatsan, I'm confused. Could you re-word that? |

Finding all Trigonometric Solutions of an Equation within a Given Interval So If I substitute, I get $1 - 2sin^2x - sinx = 1$, which is $-2sin^2x - sinx = 0$. Is there a way to simplify this further? |

Given that $s$ is an even function and $t$ is an odd function, is $s(t(x))$ even or odd? Thank you both Brian M. Scott and Austin Mohr for your help. It is greatly appreciated. |

Given that $s$ is an even function and $t$ is an odd function, is $s(t(x))$ even or odd? I would believe even. Substituting $-t(x)$ in your previous statement for $u$, for the sake of argument, $s(-u)$ = $s(u)$, since $s$ is even. Substituting back in, $s(t(-x)) = (s(t(x))$, making it even, correct? |

Given f(x), create g(x) so that f(g(x)) = x So is the solution 7x / x-1? |
