Question

Write a trigonometric table upto 90°​

Answer 1

Step-by-step explanation:

Trigonometric table :-

`\begin{gathered}\begin{gathered}\begin{array}c \bf\angle A & \bf{0}^( \circ) & \bf{30}^( \circ) & \bf{45}^( \circ) & \bf{60}^( \circ) & \bf{90}^( \circ) \\ \\ \rm sin A & 0 & (1)/(2)& (1)/( √(2) ) & ( √(3) )/(2) &1 \\ \\ \rm cos \: A & 1 & ( √(3) )/(2)& (1)/( √(2) ) & (1)/(2) &0 \\ \\ \rm tan A & 0 & (1)/( √(3) )& 1 & √(3) & \rm Not \: De fined \\ \\ \rm cosec A & \rm Not \: De fined & 2& √(2) & (2)/( √(3) ) &1 \\ \\ \rm sec A & 1 & (2)/( √(3) )& √(2) & 2 & \rm Not \: De fined \\ \\ \rm cot A & \rm Not \: De fined & √(3) & 1 & (1)/( √(3) ) & 0 \end{array}\end{gathered}\end{gathered}`

Answer 2

`\begin{gathered}\begin{gathered}\begin{gathered}\begin{gathered}\sf Trigonometry\: Table \\ \begin{gathered}\begin{gathered}\begin{gathered}\begin{gathered}\boxed{\boxed{\begin{array}c \bf\angle A & \bf{0}^( \circ) & \bf{30}^( \circ) & \bf{45}^( \circ) & \bf{60}^( \circ) & \bf{90}^( \circ) \\ \\ \rm sin A & 0 & (1)/(2)& (1)/( √(2) ) & ( √(3))/(2) &1 \\ \\ \rm cos \: A & 1 & ( √(3) )/(2)& (1)/( √(2) ) & (1)/(2) &0 \\ \\ \rm tan A & 0 & (1)/( √(3) )&1 & √(3) & \rm \infty \\ \\ \rm cosec A & \rm \infty & 2& √(2) & (2)/( √(3) ) &1 \\ \\ \rm sec A & 1 & (2)/( √(3) )& √(2) & 2 & \rm \infty \\ \\ \rm cot A & \rm \infty & √(3) & 1 & (1)/( √(3) ) & 0\end{array}}}\end{gathered}\end{gathered}\end{gathered} \end{gathered}\end{gathered}\end{gathered}\end{gathered}\end{gathered}`
