In Figure 6, notice that if one of the acute angles is labeled as θ, θ, then the other acute angle must be labeled (π 2 − θ) (π 2 − θ) Notice also that sin θ = cos (π 2 − θ), sin θ = cos (π 2 − θ), which is opposite over hypotenuseAbout Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How works Test new features Press Copyright Contact us Creators100,000 Digits of Pi
