Answer:
A=l*w
Step-by-step explanation:
so We Derive Their Formula
L=A/w
Conjecture that a and b are reciprocals
Also conjecture that a and b have the same sign
Conjecture that if a > 1 then b < 1
Answer:
Answer in simplified form is:
(sinФ - cosФ)² + (sinФ + cosФ)² = 2
Step-by-step explanation:
Given,
(sinФ - cosФ)² + (sinФ + cosФ)²
This can be simplified as:
(sin²Ф + cos²Ф - 2sinФcosФ) + (sin²Ф + cos²Ф +2sinФcosФ)
We know that : sin²Ф + cos²Ф = 1
So,
( 1 - 2sinФcosФ) + (1 + 2sinФcosФ)
or 1 + 1 -2sinФcosФ + 2sinФcosФ
or 2
Hence we got (sinФ - cosФ)² + (sinФ + cosФ)² = 2
Answer:
See below
Step-by-step explanation:
You will need to know the conversion factors for each type of measurement
example 1 pound = 2.204 Kg
or 1 pound = 16 ounces
or 1 ounce = 28.35 gm
etc
