# In the given figure, ∆ABC is equilateral.
Question:
In the given figure, ABC is equilateral. Find
(i) ∠BDC,
(ii) ∠BEC.
Solution:
(i)
Given: ΔABC is an equilateral triangle.
i.e., each of its angle = 60°
⇒ BAC = ABC = ACB = 60°
Angles in the same segment of a circle are equal.
i.e., BDC = BAC = 60°
∴ BDC = 60°

### The Importance of Unit Analysis
Unit analysis is perhaps one of the most important tasks in the solution of an engineering problem. Unit analysis is very easy to do, but it is far too often ignored. Significant errors can occur if units are incorrect. The chances of solving a system of equations where... | HuggingFaceTB/finemath | |
# Complex Cross Product Distributes over Addition
## Theorem
Let $z_1, z_2, z_3 \in \C$ be complex numbers.
Then:
$z_1 \times \paren {z_2 + z_3} = z_1 \times z_2 + z_1 \times z_3$
where $\times$ denotes cross product.
## Proof
Let:
$z_1 = x_1 + i y_1$
$z_2 = x_2 + i y_2$
$z_3 = x_3 + i y_3$
Then:
$\ds z_1 \t... | HuggingFaceTB/finemath | |
