Hi, I always suggest 2 books by author Prakash Iyer - Habit Of Winning & The Secret of Leadership and Atomic habits by James Clear...these help in building vocabulary, are simple to read, easy to understand and very practical. Hope you like them.

B) Accentuating the space between the main beats

For the ellipse

x²/16 + y²/9 = 1

Here, a = 4 and b = 3.

Area = πab = π × 4 × 3 = 12π square units ≈ 37.7 square units.

• Center: $(0, 0)$

• Orientation: Horizontal major axis (along the x-axis, as $16 > 9$)

• Semi-Major Axis ($a$): $4$ (since $a^2 = 16$)

• Semi-Minor Axis ($b$): $3$ (since $b^2 = 9$)

• Focal Distance ($c$): $\sqrt{a^2 - b^2} = \sqrt{16 - 9} = \sqrt{7} \approx 2.65$

• Major Axis Vertices: $(\pm 4, 0)$

• Minor Axis Vertices (Co-vertices): $(0, \pm 3)$

• Foci: $(\pm\sqrt{7}, 0)$

• Length of Major Axis: $2a = 8$

• Length of Minor Axis: $2b = 6$

• Eccentricity ($e$): $\frac{c}{a} = \frac{\sqrt{7}}{4} \approx 0.661$

• Directrices: $x = \pm\frac{a^2}{c} = \pm\frac{16}{\sqrt{7}}$

• Length of Latus Rectum: $\frac{2b^2}{a} = \frac{2(9)}{4} = \frac{9}{2} = 4.5$
