    Stating the amplitude

    I'm teaching myself Trigonometry & Precalculus, so please bear with me if possible. I have a book called "Mathematics for the international student".

    1. y=3six(x)
    2. y=\sqrt{7}six(x)
    3. -2six(x)

    If the amplitude of the normal sin function is 1.
    Then I'm assuming the amplitude changes when the function is the product of something.

    1. 3
    2. \sqrt{7}
    3. -2

    Correct! But we write \sin(x) in stead of six(x) to indicate the sine function.
