II Solve the ff. problems using trigonometric or inverse trigonometric functions Show illustration, define variables used and give a detailed solutions. 1. In the right triangle ABC, AB = 2, BC = 4 and ED is a line parallel to AB. Find the angle a = angle BAD which minimizes the distance L, where L = AD + ED 2. At what point on the line y = b does the line segment from (0,0) to ( a,0) subtend the greatest angle. 3. Find the angle of the largest right circular cone which can be inscribed in a sphere of radius 9 inches. 4. A statue 10 feet high is standing on a base 13 feet high. If an observer's eye is 5 feet above the ground, how far should he stand from the base in order that the angle between his lines of sight to the top and bottom of the statue is a maximum. (How far should he stand to get the best view of the statue.

Unitary Method

The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products. 

Speed, Time, and Distance

Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.

Profit and Loss

The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.

Units and Measurements

Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
