  1. The sides of a parallelogram are 4cm and 6cm, and the angle between the sides is 30 degree. Find the area of the parallelogram. (without the use of trigonometry or vector; this is for a 8th std student)

    @Daedalus sir, Thank you sir for helping. But there is a mistake in the f(x) which you have solved. It gives the nearly correct value for f(1)=2.9.... , f(2)=2.9...., but from f(3) to f(12) it gives the value so absurd. Could it be expressed in trigonometric function? Actually I expect it in a more simplified form. If we plot the points (1,3), (2,3), (3,6), (4,1), (5,4), (6,6), (7,2), (8,5), (9,0), (10,3), (11,5), (12,1) on graph paper, we get a sin or cos like curve (nearly). Plz help.
  3. I have the points (1,3), (2,3), (3,6), (4,1), (5,4), (6,6), (7,2), (8,5), (9,0), (10,3), (11,5), (12,1). Find the equation of the curve. Please solve it.

    f(x) is a ploynomial such that f(1)=3, f(2)=3, f(3)=6, f(4)=1,f(5)=4, f(6)=6, f(7)=2, f(8)=5, f(9)=0, f(10)=3, f(11)=5, f(12)=1.Find the equation of x, i.e. f(x).
