The teacher introduce the method in whatever ways necessary.

老師好！這里的whatever是融合型關系限定詞嗎？necessary前面是否省略了are?

whatever除去可以是融合型關系限定詞（引導名詞性關系分句）外，還可以是普通的限定詞（傳統語法稱為形容詞），作名詞的限定詞（傳統語法稱為定語）。比如下面詞典例句：

She will buy the painting at?whatever?price.

For?whatever?reason, he refused to speakto us. [=he refused to speak to us for some reason that we don't know]
你的句子中，whatever就是這種普通限定詞（形容詞) 使用方法，不是引導名詞性關系分句。
