This is a trigonometric identity: cosθ secθ =1
This is a trigonometric identity: cosθ secθ =1
Your goal is to verify/prove the identity by manipulating one side of the equation until it looks like the other side.
This is a trigonometric identity: cosθ secθ =1
Your goal is to verify/prove the identity by manipulating one side of the equation until it looks like the other side.
cosθ1
cosθ=1
According to trig. ratios, you can rewrite secθ as 1
cosθ
This is a trigonometric identity: cosθ secθ =1
Your goal is to verify/prove the identity by manipulating one side of the equation until it looks like the other side.
cosθ1
cosθ=1
By multiplying, you will get:
cosθcosθ
=1
According to trig. ratios, you can rewrite secθ as 1
cosθ
This is a trigonometric identity: cosθ secθ =1
Your goal is to verify/prove the identity by manipulating one side of the equation until it looks like the other side.
cosθ1
cosθ=1
By multiplying, you will get:
cosθcosθ
=1
1=1
According to trig. ratios, you can rewrite secθ as 1
cosθ
This is a trigonometric identity: cosθ secθ =1
Your goal is to verify/prove the identity by manipulating one side of the equation until it looks like the other side.
cosθ1
cosθ=1
By multiplying, you will get:
cosθcosθ
=1
1=1
According to trig. ratios, you can rewrite secθ as 1
cosθ
You just verified the identity.
So, Verification Format Looks like this:
cosθ secθ =1
cosθ1
cosθ=1
cosθcosθ
=1
1=1
