Answer:
Mehran Tavakoli Keshe was born in Iran in 1958, son of an X-ray engineer. He was introduced to the world of radiation and nuclear science at a very young age. In 1981 he graduated from Queen Mary College, University of London, as a nuclear engineer specializing in reactor technology system control. He has spent the years since then completing a system for the production of gravity and energy using a radioactive hydrogen-fueled reactor that is clean and safe. He has covered all aspects of the design of a new plasma nuclear system from the very beginning to its present stage. This has included the design, the fuel, testing and practical applications. He has concentrated on completing the full range of his technology for launching into the scientific world and industry. The intellectual properties related to this technology were transferred to Stichting the Keshe Foundation.
Answer:
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:
- Sine and cosine
- Tangent and cotangent
- Secant and cosecant
The cofunction identity states that the value of a trigonometric function of an angle equals the value of the cofunction of the complement angle.
<u>(Remember that complement angles are two angles whose sum is 90)</u>
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:
- cos (90-θ) = sin (θ) (sin is the cofunction of cos and θ is the complement of 90 - θ)
- Cotangent (90 - θ) = tangent (θ) (tangent is the cofunction of cotangent and θ is the complement of 90 - θ)
- Cosecant (90 - θ) = secant (θ) (secant is the cofunction of cosecant and θ is the complement of 90 - θ)
C? I think.
Sorry If I'm wrong. Only C makes sense.
