%using tanh(x) command to find value of tanh(0.2)
%Q6) calculating velocity of a falling ball when it hits the earth
%assuming no friction
%h=5, released 5m above ground
%Resistance in series= R1+R2+R3+R4
%R=resistor which has a value of resistance.
%Resistance in parallel = (1/R1+1/R2+1/R3+1/R4)^-1
%Find time taken to fill up tank
NULLolumetric flow rate= Area x flow velocity
%Q7) swims 60m east then 25m south and dive 30m below water surface.
%Calculating minimum distance if swims in a straight line.
%Use pythogoras theorem
%First triangle with 60,25 and hypotenuse.
%Now, the minimum distance wo
% linspace -> Points equally distanced within two values.
%Example: 6 points equally distributed within 0 and 10.
% Example:21 points equally spaced within -20 and 20.
% Q2) cos(x)= cosine of arguments in radians form.
