Question

Mathematicians who worked for  the develodment of  trigonometry?
list the formulae in trigonometry?
uses of trigonometry in various field?

Answer 1

the formulas for trigonometry are as follows:

sin=opposite/hypotenuse.
cos=adjacent/hypotenuse.
tan=opposite/adjacent
and the reciprocals are cosec,sec,cot.
the mathematicians who worked for development of trigonometry are srinivasa ramanujan,archimedes, Aryabhatta

Answer 2

• Ptolemy (100 178 CE)
• Liu Hui (3rd century CE)
• Aryabhata (476550 CE)
• Abul Wafa of Baghdad
