1/4t + 3/5= 2/5 - t

  • algebra -

    Is it

    (1/4)t or 1/(4t)?

  • college algebra -

    (1/4)t

  • college algebra -

    d/dx(sinx+cosx)

  • college algebra -

    (1/4)t + 3/5= 2/5 - t
    => (5/4)t + 3/5 = 2/5
    => (5/4)t = -1/5
    => t/4 = -1/25
    => t = -4/25

    Strictly the equation should read

    (d/dx)(sin(x) + cos(x))

    => (d/dx)sin(x) + (d/dx)cos(x)
    => cos(x) - sin(x)

    The differentials of sin and cos should be learned. You can demonstrate the results by differentiating their respective series
