\(\cos(x) \times \tan(x) = \sin(x)\)?

cos(x)×tan(x)=sin(x)\cos(x) \times \tan(x) = \sin(x)

Proof:

sin(x)=oppisitehypoteneuse\sin(x) = \frac{oppisite}{hypoteneuse}

cos(x)=adjacenthypoteneuse\cos(x) = \frac{adjacent}{hypoteneuse}

tan(x)=oppisiteadjacent\tan(x) = \frac{oppisite}{adjacent}

cos(x)×tan(x)=adjacenthypoteneuse×oppisiteadjacent\cos(x) \times \tan(x) = \frac{adjacent}{hypoteneuse} \times \frac{oppisite}{adjacent}

adjacenthypoteneuse×oppisiteadjacent=oppisitehypoteneuse\frac{adjacent}{hypoteneuse} \times \frac{oppisite}{adjacent} = \frac{oppisite}{hypoteneuse}.

oppisitehypoteneuse=sin(x)\frac{oppisite}{hypoteneuse} = \sin(x)

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

  • Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
  • Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
  • Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
  • Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

What are you considering? Do you mean ''Prove that cos(x)×tan(x)=sin(x)\cos(x) \times \tan(x) = \sin(x)''?
