    Hi,

    y = 5/sex^3(7x)
    This is equivalent to 5/1/cos^3(7x)
    BUT I don't see how the second line = 5cos^3(7x) because isn't 5/1/cos^3(7x) = 5/cos^3(7x)??? Because = 5/1 * 1/cos^3(7x)...

    Thanks in advance

    5/sec3(7x) is

    5/1 divided by 1/cos3(7x)

    so 5/1 multiplied by cos3(7x)/1

    = 5cos3(7x)
