4cos(theta)+3sin(theta)=(10/r)

The general equation of such cosine function is:y=acos(x-phasedifference), y=displacement a=amplitude x=angular displacement =(angular velocity)*time =(2pi/time period)*time Therefore, the equation can be written as: y=2cos[x-(pi/4)]..........(a) or,y=2cos[(2pi/pi)*t-(pi/4)] ...

x^6+3x^3+2=0 It can also be written as: (x^3)^2+3(x^3)+2=0...........(1) Let a=(x^3), then we may rewrite equation (1) as: a^2+3a+2=0 or,a^2+a+2a+2=0 or,a(a+1)+2(a+1)=0 or,(a+1)(a+2)=0 either,a=-1 or,a=-2 that is (x^3)=-1 or (x^3)=-2 Therefore, x=-1 or x=cube root of -2 this ...

metals are the good conductor of heat. hence, metals can gain heat by contact. so, the cup with the metal spoon will cool faster.

cause the air comes in thermal equlibrium with your body... and it depends upon the heat that your body looses...i guess so.
