How does the unit circle allow the trigonometric functions to be defined for all real numbers instead of just for acute angles?

Every point in the unit circle is identified either by its coordinates (x,y) or by the angle it forms with the x-axis, \alpha.

The trigonometric functions associate with every angle \alpha and the correspondant (x,y) coordinates the two values

\cos(\alpha)=x,\quad\sin(\alpha)=y

This procedure can be done for every angle \alpha, so you don't have to work with acute angles only.

Dean made a triangular wall shelf.
zhannawk [14.2K]

Answer:

The shelf is not a right triangle

Step-by-step explanation:

Given

Sides = 14, 8, 8

Required

Determine if it is a right triangle

To do this, we make use of Pythagoras theorem which implies that; the square of the longest side = the sum of the square of the two other sides.

So, we have:

14^2 = 8^2 + 8^2

Evaluate all squares

196 = 64 + 64

196 = 128

The above is not true because:

196 \ne 128

<em>Hence, the shelf is not a right triangle</em>

25% discount for AED 4000
Lostsunrise [7]

Answer:

The 25% discount on AED 4000 will be: 1000 AED

Step-by-step explanation:

Given

  • The amount = 4000
  • Discount = 25%

In order to determine a 25% discount on the amount AED 4000, all we need means is to multiply 25/100 or (0.25) by 4000.

i.e

Discount amount = 25% of 4000

                             = 25/100 × 4000

                             = 0.25 × 4000

                             = 1000 AED

Thus, the 25% discount on AED 4000 will be: 1000 AED
