Dear diary
I am really excited because I bought a lottery ticket and it is possible that I can win the lottery. If I win the lottery then I'll spend that money in different ways. First of all I buy a new watch for dad and a jewellery set for mom and an imported makeup kit for my sister and a smart watch for my younger brother then I'll spend the rest of the money on buying a novel series for me. I hope that I will win in the lottery.

Step-by-step explanation:
Varahamihira was a mathematician, astrologer, and astronomer. His prominentmathematical work includes the discovery ofthe following trigonometric formulas:Varahamihira also improved the accuracy of Aryabhatta's sine tables. Varahamihira also defined the algebraic properties of zero and negative numbers.
Great Indian Mathematicians 3 : Varahamihira.Varahamihira (505 – 587) was an Indian astrologer whose main work was a treatise on mathematical astronomy which summarised earlier astronomical treatises. He discovered a version of Pascal's triangle and worked on magic squaresVarahamihira’s Contributions of Trigonometry
Varahamihira’s mathematical work included the discovery of the trigonometric formulas
Varahamihira improved the accuracy of the sine tables of Aryabhata I.
Arithmetic
He defined the algebraic properties of zero as well as of negative numbers.
Combinatorics
He was among the first mathematicians to discover a version of what is now known as the Pascal’s triangle. He used it to calculate the binomial coefficients.
Optics
Among Varahamihira’s contribution to physics is his statement that reflection is caused by the back-scattering of particles and refraction (the change of direction of a light ray as it moves from one medium into another) by the ability of the particles to penetrate inner spaces of the material, much like fluids that move through porous objects.
