ফাংশন f(x) একটি বিজোড় ফাংশন যদি f(x) = - f(-x) হয় এবং একটি জোড় ফাংশন যদি f(x) = f(-x) হয়।
যখন f(x) একটি জোড় ফাংশন হয় তখন
যখন f(x) বিজোড় ফাংশন হয় তখন
গণনা:
প্রদত্ত:
ধরি, f(x) = cos x
আমরা দেখতে পাচ্ছি যে, f(- x) = cos (- x) = cos x = f(x)
সুতরাং, cos x একটি সমান ফাংশন।
যেমনটি আমরা জানি যে, যখন f(x) একটি জোড় ফাংশন হয় তখন
সুতরাং, সঠিক বিকল্প হল 1
