According to the cofunction identities, cosine (90 degrees minus theta )equals cotangent (90 degrees minus theta )equals and cosecant (90 degrees minus theta )equals

cosine (90-θ) = sine (θ)  

Cotangent (90 - θ) = tangent (θ)

Cosecant (90 - θ) = secant (θ)

Explanation:

The cofunction identities show the relationship between one function and its cofunction regarding complement angles.

Recall that the 3 pairs of cofunctions are:

The cofunction identity states that the value of a trigonometric function of an angle equals the value of the cofunction of the complement angle.

(Remember that complement angles are two angles whose sum is 90)

So if we have an angle θ, then the complement is 90 - θ (since θ + (90 - θ) = θ +  90 - θ = 90)

Thus we have that:

the historians cited in the article all agree with one another about the cause of the civil war. despite coming from different backgrounds and cultures, the historians agree that slavery was the root cause of the civil war. the fact that all these historiansgenerally agree with one another makes their shared viewpoints more reliable and valid, especially because the historians have different backgrounds and all work for the well-respected institutions of howard university, clemson university, and the university of colorado.
