    Mathematics: Post your doubts here!

    Here is how: Part (i) sin θ + cos θ = 2(sin θ − cos θ) sin θ + cos θ -2sin θ +2cos θ = 0 3cos θ = sin θ 3= sin θ .....cos θ sin θ = tan θ cos θ tanθ = 3 (expressed) Part (ii) Hence solve the equation sin θ + cos θ = 2(sin θ − cos θ), for 0 ≤ θ ≤ 360 so use the expression fain...

    Useful stuff compiled ( For O-level )

    Explanation why it is C: 25cm --> 120 C 1cm --> 120/25 = 4.8 C 15cm --> 72 As it is starting from -10, it would be 72-10 = 62

    I dont remember exact definition now... formulas are: Specific heat capacity: Q = mc Δ Θ c= specific heat capacity m= mass Δ Θ: change in temperature Q= energy provided. Heat capacity: Q= cΔ Θ Latent Heat of Fusion Latent Heat of Vaporisation l = latent heat of vapourisation/fusion

    Actually our teacher said it too it isnt in the syllabus, but we should prepare it. like Alkaline and Acidic fuel cells... when H2O is added to HCL, it forms H30 and CL, something similar would be applicable here I believe.
