Answer:
- [tex] \tt {sin}^{2} x + cos^{2} \longrightarrow1[/tex]
- [tex] \tt \: \frac{ {sin}(x )}{cos(x)} \longrightarrow \: tan(x)[/tex]
- [tex] \tt \: 1 + {tan}^{2} (x) \longrightarrow \: {sec}^{2} (x)[/tex]
- [tex] \tt \: \frac{1}{tan(x)} \longrightarrow \: cot(x)[/tex]
- [tex] \tt \: \frac{1}{sin(x)} \longrightarrow \: csc(x)[/tex]
- [tex] \tt \: \frac{1}{cos(x)} \longrightarrow \: sec(x)[/tex]
- [tex] \tt \: 1 + cot ^{2} (x) \longrightarrow \: {csc}^{2} (x)[/tex]
